I've noticed several smartwatches on Amazon with thousands of positive reviews for less than $50. I've linked to one that's $27.98 with 15,000 reviews, but there are lots of others.
Frankly, I'm not sure how I would use it. I'm just curious to see if I'm missing out on anything. I'd probably continue to use my Timex Tapscreen HRM for running intervals so it wouldn't have to be my #1 running watch. I don't need or want a GPS function. The heart monitor and sleep quality functions sound interesting, but really, don't people know whether they've gotten a good night's sleep? Anyone have a recommendation for an inexpensive smartwatch. I'll be connecting it to a Samsung Galaxy S9+.
