Pretty decent youtube review.
My brother’s short summary to me about his experience with the watch when I asked him:
Watch issues. The “find phone” feature doesn’t work very well on iPhone.
Battery life is awesome. 83% left and been off and on wearing it the last week. (I don’t wear it at night)
I think it’s worth $20, but when you factor in shipping…I don’t know. This watch has far less features than the cheap Chinese smart watches you find priced similarly on eBay. The hardware seems to be better quality though. The Wyze Watch has a long way to go before it will be where it should be.
