I often see comments about weak backlighting. In addition to various sports watches, I did not wear other smarts, maybe they have some kind of particularly bright screen, and so, the backlight and screen clarity of the polar, in my opinion, will be better than many others from the same category and purpose, or at least on the same level. The backlight is adjustable, it works automatically when the position of the hand changes, which is very convenient in the dark, when it turns on by itself and you do not need to press the buttons. The accuracy of gps, like that of all similar sports brands, did not notice anything special either as a plus or a minus. There are no rattles like games in the watch, who even guessed to shove such things into sports gadgets? They do not pay by the clock, there are no cards, there is no downloading music directly to the watch, as on some similar gadgets, which can sometimes be useful, although it eats up the battery, but the price is lower than that of competitors with such functions. In general, I would rate them at 4.5, there is something to strive for, just as competitors do not have an ideal, everywhere there are pluses and minuses, but there is no such rating here, so I will round up to 5 :)
