Does what it says on the tin,
This review is from: Glass Full Body Analyser Body Fat BMI Hydration Bone Mass Digital Bathroom Scale
Scales arrived very well packaged and instructions are straightforward enough to follow.
They're slim in design and are easy to use.
The only problem (although no biggie really) is that the information is displayed on a cycle: weight, bmi, hydration, % body fat, muscle mass etc and it only stays on the screen for a few seconds. If you want to record this information. It's easier if someone else can help you here, one writing it down and another checking it.
I had to get on several times to enable me to record all the info.
