Review: Favorite Fitness Watch - I bought my first polar watch back in 2012. I like the weight/calorie/step feature and the various training modes. I do not connect to internet because I do my own program and this works well for me. I just want the basics to help me control my weight. Nothing else needed.
Review: Ten months trying to persevere. No more! Utter garbage. Buy at your own risk - The only thing about this piece of crap that is marginally decent is the heart rate monitoring and even that has issues. The pairing to a phone, the syncing to the Polar App, the app itself, the way the band connects, the useless extras like Sleep Tracking and the useless but intrusive “blog” are all rubbish. I bought this in March 2022 and have been persevering with it for the past 10 months. I am fed up, sick and tired of dealing with it. The GPS feature is worse than useless. About 60% of the time, it fails to connect at all. The vast majority of the remaining times, it will lose connection during the ride resulting in erroneous distance and route information. I always ride with Strava and it, plus my analog cycle computer, always match. If the feature does not work. Fix it or eliminate it! The pairing the watch to a phone is an exercise in frustration. Syncing the phone to the polar app is usually an ok exercise but not always. Again frustrating. Fitbit has a way better mechanism for attaching the band. This is a poor mechanism. There is too many useless features like the Sleep Tracking stuff. I know if I had a good sleep. Further, it is not accurate. I will wake up rested and feel I had a great sleep and this POC will advise that my sleep was poor. Finally, I wanted a watch that would show my heart rate when I was in the middle of exercising. This POC claims to do so but does not. The screen goes black after a few seconds. When I am in the middle of climbing or sprinting, I can’t be flicking my wrist to see if this POC will bother to show my current heart rate. My old Polar FT7 constantly showed the current heart rate. The reason I bought this POC was I had had such good results with the FT7 and the even older one I had before that. Never again. I will buy an Apple, Fitbit, Garmin or anything else before I will buy another Polar POC.

### ⭐⭐⭐⭐⭐ Delivers what I wanted most: Data!
*by M***A on May 31, 2023*

I shopped around quite a bit for a replacement for my Amazon Halo which was my first fitness tracker. A lot of trackers have extra features that have nothing to do with fitness so I don’t need them. I was looking for accurate data and this seems to do really well. The battery only lasts about 3 days but that’s not a big deal for me. It only takes about 30 minutes to charge so I can just do it while I shower. I only wish I had spent more and gotten the Ignite with the built-in GPS. I didn’t think I would want that feature until last night during my team’s dragonboat practice. I needed to have my phone on me to connect to its GPS and I don’t like having my phone on the boat for fear of it getting wet. It tracked every moment, and I could go back and see the time, speed, heart rate and distance of every part of the practice on the map. Way freaking cool!! Oh whatever complaints people had about screen delays, they must have worked that out because I haven’t had that problem.
