Love the Body Fat Measurement & Batt Life
Brought this a couple of days ago and very happy with all of the new features, including the accuracy of the body fat measurement. Had the always on display on since 8:30am and its now 3pm and I'm sitting at 82%. In all honesty I find most of the negative reviews claiming only a few hours of battery and overheating to be disingenuous out favor towards another brand. They should be made to show receipts before being allowed to post a review.

Disappointed
Please read reviews! This thing didn't work at all it wouldn't even turn on. When we contacted the seller they said it was the charger and they would send us a charger but the watch itself would never turn on. I'm happy they were willing to make it right but hubby found it was reconditioned and said nope just send it back so we did and our refund was given!
