Query: This scale works great!

This scale does exactly what it said it does. It measures weight, body fat for up to four people. The button to turn it on and off is located right at the foot so you dont have to bend down to turn it on. The buttons on the scale are also easy to just push with your toes. It keeps track of your last weight. One thing I would say I dont like is having to turn it off and back on in order to switch users but other than that it is a very nice scale and easy to use. It is also very quick on displaying the weight and fat numbers unlike other scales that take forever.
