The balance has also indeed a metal (?) - Rack under the glass plate, but is set to small rubber plugs - that does not damage the tiled floor.
One more thing for handling: Usually I only knew balances that you tap before you climb on it; this one is on it easily and the weight is displayed immediately. It was first used to (I had to read or only once, why the scale apparently did not work), but when you know it is absolutely no problem.
The balance earns the 5 star absolutely! Of course it shows no body fat values, etc, if you want you have to grab the already deeper into their pockets. For the price it is, however, not be beat!
++ Price
++ Battery included
++ Beautiful and simple design
++ Rubber feet
(~ Solid stand & straight posture on the scales are a must! (But is no star deduction))
