Top critical review
If I were only 2/3 my height
24 September 2018
This is a great simple device. It's annoying to set up just like an old school digital watch but once it's going it should just work, right? Well mostly right. It works unless my arm is fully extended. To get an accurate reading, I have to hold my wrist up, wait for it to sync (maybe 5-10 secs), otherwise it's all over the place. It's happily announced my death several times.
It seems like at 6' my arms are a little too long. I'm sure it worked fine for the people testing it in China. If they tested it. It will probably work fine for you too, if you are smaller than me.
