Practical, simple and universal. Thanks to the great balance, you can place practically anything in it, no matter if it is a mobile phone or a tablet of any size. I personally placed both my mobile phone (Apple Iphone 11 with a shockproof case from Mobilfox) and the mobile phones of acquaintances or colleagues, who also liked this stand very much. In my work I will use it mostly with tablets and I was surprised that even tablets with a size of 13 inches and a weight of about 1 kg had no effect on the perfectly placed center of gravity of the stand.
In case of any uncertainties, I recommend increasing the model in the slicer by 5-10%.
