Review on Enhanced Ergonomic Laptop Stand with Phone Holder, Side Mount Clip, and Monitor Expansion Bracket. Portable & Slim Foldable Stand to Boost Office Efficiency. by Raquel Perkins

Seems to work as advertised. I bought it to use with an Android phone and a lapdock. I attached a metal washer to the outside of the phone cover. Works perfectly. So I put the device on a wireless charging station and charged the battery. But after about 15 minutes the metal disk was so hot that I couldn't touch it. Not good. So I bought a second case. One with a disc for laptop use and the other for everyday use with a wireless charger. And I definitely wouldn't put it on the bare surface of the phone. I just bought the S21 Ultra I wouldn't risk ruining the finish for anything.
