Отзыв о Умные часы Polar Vantage M, черного цвета от Lc Qu ᠌

Synchronization with my phone (pure android, no skins) doesn't always go smoothly. It may not transfer all the data at a time, or not synchronize the first time, but by itself when it synchronizes in the machine (in the background) - everything is fine. Tried several times to synchronize with iPhones - everything is fine. So it's more of an incompatibility with my phone. Sometimes steals my meters in the pool. I swim in a 25 meter pool: when I just swim freestyle - there are no problems, everything clearly shows (number of strokes, pace, pulse (!), distance). But when I swim with shoulder blades, or with a board (he doesn’t count meters with it at all, since there are no strokes), he starts not counting part of the distance. And after them, he and the crawl already sometimes counts incorrectly. I haven't tried it in 50 meters yet, but I think there will be fewer errors. Well, you can probably add not the most convenient strap buckle.
