Review on Polar Vantage M Smart Watch, Black by Hideo Tsushi ᠌

They say that only a negative experience can inspire you to write a review, and in the case of this watch, this is 100% true. I bought it a month ago and every day I am more and more convinced that I threw away my money in vain. So: 1. Very weak illumination, it is very difficult to navigate in the evening on the run. 2. The most painful problem for me is the disgusting work with intervals. There is an interval mode, but for some reason it only works for equal segments. Those. if I want to run 400 meters 4 times, then ok, but if 2 times 400, and then 3 times 600 - this is no longer possible. Perhaps I could not figure out the settings, but those. Polar support was silent on my question. As I was told in the comments below (thanks, guys!), the watch has such an opportunity and it works, but everything is not implemented very user-friendly and, moreover, only through the Flow online service, this function is unfortunately not available through the application. Dear Polar, I hope you take this into account. Also, if you indicate in the interval mode that the beginning of a new interval is started manually, the clock starts to get stupid hard and do not want to turn on the new interval. 3. 2 times in 4 weeks of use they rebooted themselves during training without saving progress. 4. Tracking sleep - I sleep from 22.00-07.00, the clock cheerfully reports in the morning: "you slept 5 hours 37 minutes." Funny math. 5. Through time are synchronized with the PC. Just at will. 6. Notifications from a smartphone are also optional and every other time.
