Query: Consistent and accurate, but self-activates sometimes

I have had this scale for probably 5-6 years now, and it's been very consistent and accurate, both in terms of weight and body fat measurement, for both my wife and I (~7% fat and ~24%, so very different ranges).On the down side, sometimes the scale will turn itself on. It's like the weight of the scale itself is pressing down on the buttons. So just be aware of it if you own it.
