Good purchase
I have several products from Xiaomi. All quality products.
The material of this keyboard far exceeded my expectations. It's a heavy duty one, weighs around 900g and seems to be well made. Material seems to be some sort of steel + quality plastic + quality rubber. The inferior part of the keyboard are the few coloured keys, the plastic seems to be inferior to the rest. It also looks very good. Unfortunately I didn't get to try it yet cause it's a gift. You of course need to prepare 2 x AAA batteries to power it up. Seller also shipped it out the next day I've ordered it. It took just over a month to receive to MT, EU.
