great for running, although the gps is a bit slow. No real complaints as a running watch!A lot of the displays could use work. Things aren't labeled. None of the graphs scale at all, so they look totally flat w/ just 2 pts labeled (e.g. heartrate is just s wiggly line at about 0.15 on whatever scale it is, whether my pulse is 49 or 115 it looks the same).The "moveIQ" feature just doesn't work as well as a fitbit; it isn't customizable, and it tells me I need to move while I'm mid walk or doing yardwork, and then it says "move bar cleared" when I'm sitting motionless. That needs work!Not to pile on, but w/ no phone paired/no bluetooth, and default settings (~1.5s backlight, gps only during runs, heartrate on), I get like 3.5d of battery life instead of the claimed 7d.OK, that may sound negative, but overall it's hands down the best I've had for running. Just the rest of the (less important) stuff needs some (mostly software) work.It isn't too big (I got the 45s as I have tiny wrists for a dude). I think there's a lot of potential here, and "fresh from the box" it does what I need for running. The pc/web apps work fine and have lots of info (again, graph scaling is terrible; c'mon guys the code for this has been public since before any of y'all were born, it's not hard). It seems to do well on route logging, distance, pace, etc. although I haven't tried to rigorously calibrate it (just using it's defaults, but it seems ok so far).So, very high marks for a casual runner. If I really wanted a lifestyle fitness monitor I'd probably pick a fitbit, like my wife uses tho. But I expect this will improve (already a lot of s/w updates, some pretty substantial).---- followup---I'm increasingly skeptical of the heart rate monitor accuracy. It says my sleeping HR is 41-45; pretty sure I'd be dead? walking across the room it frequently says 115. reading? anywhere from 51-90..wth? Lifting for 45m? 65 while lifting but randomly jumping to 100+ when I'm resting for a longer break. I'm exactly avg size/wt for adult male, and in "meh" shape after 2020-21, very casual run/lift a couple times a week. In the past i've checked and gotten much more reasonable & consistent HR (60-65 resting, ~100+exercising, etc.) manually. Still happy w/ the running watch time & distance & logging tho.How do we know how much we love someone or something? By how much/how little we rejoice when being reunited. Back in August 21', my Garmin Forerunner 230--my second watch of that model--broke when I slipped on a pothole during a long distance run in Jerusalem. Because I wear the face of the watch on the under wrist, it broke while I was breaking my fall. I loved this watch, even though it was an older model that had been phased out of production, and I purchased both it and the previous unit as "refurbished" watches on Amazon. I wore this watch in tandem with a Garmin chest strap to get the most accurate heart rate reading I could during these long runs. When the watch broke, I didn't bother ordering a new one, as I was overseas and preferred to wait until I would be back home in the USA in couple of months. While I missed not having a watch to measure the distances and paces of my runs, I felt a certain "release" and freedom to run without the compulsion to always look down at my watch to see how many miles were behind me, or what my running pace was. I felt free to simply "be in the moment" and enjoy the scenery without defining the moment by my live stats......Until four months later, when I started to miss my Garmin. I was going to look for another outdated, refurbished Forerunner 230, but when I looked for it on the Amazon site, I kept being directed to a new Forerunner 45 instead. The display was very different from the 230, and as I read about its features, I thought it has too many "bells and whistles" that I don't need....like the "body battery" feature, concerning which I was quite cynical as to how accurate such a feature could really be (similar to my cynicism about my previous watch's claim to be able to measure my VO2 max). Notwithstanding, at only $139, I considered the watch a great value and purchased it.Just one week into wearing it, I can't take it off...I'm addicted to it! The most pleasant surprise has been the accuracy and convenience of the built in heart rate monitor, which over the past three long distance runs has proven itself to be every bit as good and accurate as the Garmin chest strap I formally wore with the 230. Now I have around-the-clock, 24 hour heart readings, including my resting heart beat, which again is very accurate (mind you, I wear the watch with the face on the under wrist, which probably provides for a more accurate pulse reading). And the feature I was most cynical about, the "body battery," has also proven itself a delightful and accurate edition to the repertoire of my watch's features. How do I know it is accurate? Simply because it accurately expresses exactly how I feel! It is really amazing. Even the clock display, which I thought I would never grow to like--it displays the minutes beneath the hours--has grown on me in just a week, and no longer bothers me. Whereas I used to take off my other Garmins when I went to bed, as they didn't have any features I felt I need during the night, the 45 model begs to be worn around-the-clock, as it provides vital information--heart rate, sleep, and body clock summaries--the next morning. With these features, especially the "body battery," the watch is tutoring me as to what my realistic fitness aims should be, on a particular day. If the body battery displays a 25/100 charge, I probably shouldn't attempt a 12 mile run, like I did nonetheless yesterday, I failed to complete it before hitting "the wall." I highly recommend this watch an model, which is becoming a dear, dear friend.I’ve waited for five months before writing a review on the Garmin Forerunner 45. I wanted to be sure of my views and that confidence could only emerge with repeated usage over time. Hence, after about more or less 500kms of running in the past five months, I am confident of my review accuracy.So I wanted a fitness watch, solely to monitor my runs, walks and physical activity. It took me some time but I homed on to the Forerunner 45 considering both my budget and specific purpose.The Forerunner 45 is not a smart watch with versatility and functions of the Apple Watch but it performs some useful smart functions of alerting you once a call or message is received. Leave that aside as my purpose was not a full-scale smart watch but a physical fitness smart watch.And I could not have been happier. The Forerunner 45 is beautifully crafted and ergonomically designed. I have a thin wrist and the watch size was perfect for me. I find it fits snugly and the watch band has excellent grip and sturdy latching mechanism.It is very accurate. I matched the iPhone measurements and based on my previous measured runs I found the watch to be consistent and correct in measurements. Plus, it’s a Garmin product, they produce GPS receivers that are fitted on aircraft and ships the world over. So accuracy is assured.Battery life is very good, I need to charge it every third day or preferably the second day, and the charging takes little time. I think about 30 minutes or so to full charge from half charge status. In all probability, if you don’t use the GPS, the battery life will be a week. The point is battery life is very good and charges fast.The push buttons for accessing the menu are intuitive and I never felt the need for a touch screen functionality. When your fingers are sweaty and you are doused in sweat, you need hard interfaces and the push buttons are ideal. At least I feel so. The menu navigation takes a little time to get used to but it’s not a worry at all. Be a little patient in the initial stages to learn the settings. There is some complexity in settings such as alerts every km or units or targets etc. I wonder how much of these can one gainfully use, but there are a number of user settings that can be done. I like the feature that when it’s dark and you are exercising, the dial lights up when the wrist is turned to your face for you to see the exercise status, and then switches off on its own. That saves battery too. Good engineering.Yes, you may have read that the GPS lock on takes some time and I too have noted that occasionally. But off late, after upgrading the software, I have not noticed any delay in locking on to the GPS. It takes less than a minute but I have had occasions that the lock on has taken up to 15 minutes. In a way, a few minutes to achieve lock on is good as I warm up and stretch during that time. So if it takes a little while, I am fine with it. But please ensure that you upgrade the software upon release of a new version. This should happen automatically on syncing the watch with the Garmin App on the phone.The mobile app is well designed and syncs well with the watch. The details of your walk, run, duration of exercises, VO2, calories, sleep activity are all updated and aggregated. For instance, it’s a good feeling to see the amount you’ve walked or run in a week or a month or a full year. And you do get motivated to exercise more if the data shows a declining trend. Your best effort is also highlighted from time to time. In all, the Garmin app is neat, well designed and presents the data in great detail. For example, you can access additional details of your run, your heart rate, body battery and also stress level. You can compare yourself with the rest of the population that is using Garmin app. Frankly, I have not accessed in great detail the data measured by the Watch, its quite a lot. But the watch is very sensitive. I was once running and a wire from a tree was hanging loose, I ran into it unknowingly and it stabbed me on my cheek bone...I stopped dead on my track and the watch started to vibrate wildly exclaiming a sudden stop and then went on to dial the emergency number. I was amazed. This could have actually been an emergency if the wire has impacted my eye. Hence, the watch is very sensitive to alert any fall or sudden stop. I can vouch for that.So for QUALITY, BUILD, ACCURACY, APP SUPPORT and BATTERY...the Forerunner 45 is a great fitness watch.Estou avaliando com apenas 3 estrelas devido às informações muito pobres no manual e no site da Garmin (ver adiante). O que mais gostei: a visibilidade do display é muito boa, mesmo com sol. Gostei também do sistema de navegação com botões. Eu possuo um Polar Ignite que usa o sistema de toque na tela e possui apenas um botão; prefiri o Forerunner 45, que, na minha opinião, funciona bem melhor neste aspecto.O monitor cardíaco funciona bem, mas é mais lento que os modelos que usam sensores com eletrodo no peito; acredito que seja uma característica dos sensores de pulso, mas isso não compromete o uso. O relógio é confortável de usar (melhor que o Polar Ignite que, no meu caso, deve ficar bem apertado no pulso para o frequencímetro funcionar).O GPS demora um pouco para sincronizar mas depois funciona bem. Possui opções de GPS Normal, GPS+GLOONASS e GPS+GALILEO, mas não notei, até agora, diferenças entre elas. Ter um GPS é interessante para dar uma noção das distâncias percorridas e altitude mas não serve se você precisar de indicações bem precisas (nenhum GPS comum serve para isso).O meu modelo é preto e vem na cor fosca; gostei do acabamento, a pulseira é flexível e confortável. É discreto no pulso e não é tão grande como pensei que seria. O Forerunner 45 tem diâmetro de 42mm e o 45S tem 39mm (lembtrando que este último tem a pulseira menor).No mais, o dispositivo vem com diversas funcionalidades oferecidas pelos modelos atuais de monitores, tais como smart coach, monitoração de sono, VO2max, etc..etc... (mas não possui o equivalente à função Serene, que o Polar Ignite tem). Não gostei muito: da duração da bateria (talvez uns 3 dias, mas depende do tipo de uso). O carregamento da bateria também é meio "primitivo": é feito com um cabo especial com pinos que se encaixam no relógio; a outra ponta é um conector USB que deve ser conectado numa fonte (que não vem junto). Não passa a sensação de ser muito durável; neste aspecto o Polar Ignite é bem melhor: o cabo possui um acoplamento magnético que "gruda" relógio, rápido e fácil. Não gostei nem um pouco: do manual muito precário e da falta de informações sobre o uso, mesmo no site da Garmin. Esta precariedade na interface com o usuário se estende até mesmo no uso do relógio. Por exemplo, durante o treino aparecem grupos de números no display, tais como: 1.8 89 215. O que isto quer dizer? Sim, aparece um "Help" muito rápido e apenas uma vez quando se pressiona o botão para início do exercício. Mas, na minha opinião seria bem melhor mostrar no display algo como: Zona 1.8 89 bpm 215cal.Outro exemplo: no Manual aparece como especificação que o aparelho resiste a uma pressão equivalente a 50m de água. Então, serve para natação? Apenas saberemos disso após uma busca minuciosa no forum da Garmin... Lá dizem que não serve para natação (parece que o sensor de pulso deste modelo não funciona bem na água).No quesito de informações claras e especificações, a Polar é bem superior, na minha opinião. Conclusão: como disse, estou avaliando com 3 estrelas devido à falta de informações e dificuldade para descobrir as funcionalidades do dispositivo. Até hoje fico com a sensação de que poderia estar aproveitando melhor meu Forerunner 45 se fosse mais fácil descobrir como fazer isso. Aqui, julgo que a Polar seja superior ; seus produtos são bem mais intuitivos de usar.Todavia, o sistema touch screen do Polar Ignite é tão incômodo de usar, epecialmente durante um exercício, pois o display fica apagado e nem sempre acende com o movimento do braço, que preferi ficar com este Forerunner 45.Bateria dura mais que os relogios de outras marcas. Quando tiro o relógio ele não fica com a luz verde (de frequecia cardíaca) acionada, o que ajuda muito para economizar a bateria.A imagem não é das mais bonitas, mas para correr é perfeito, da para ver o tempo sem os deleis que as telas que ligam com o movimento levam.Em relação a música, não consegui usar o comando de mudar de música enquanto corro, talvez não tenha essa função mesmo.Comparei a frequência cardíaca com outros frequencimetros como o da polar (OH1) e os valores bateram.Mas ele serve para marcar as minhas corridas de forma confiável sem eu precisar levar o celularExcelente produto. Muito bom a qualidade! Vale o preço!!!Wonderful again by Garmin! Cheapest forerunner edition, better than forerunner 245.Pros-colour display-utmost accurate gps tracking and heart rate-colour straps for this edition, available at amazon.in-vo2 feature-display size is fit (not too big not too small)- battery backup as mentioned by garmin-decent data display options while on activity trackingBeen using for a month and distance,steps, Heart rate tracker seems to be accurate.Battery life is good and comes atleast for a week.Thanks Garmin for shifting my running to next level.!
