Review on 📱 2021 Upgraded VANMASS Phone Holder for Car: Industrial-Strength Suction Cup Mount for Dashboard, Windshield, and Air Vent - Compatible with All iPhone & Android Cell Phones (Space Gray) by Shawn Sims

Unfortunately, the most important feature of this product is the sticker. And it doesn't work at all. I bought it so I wouldn't have my phone on a heat/cold vent. I followed the directions, left the pad on the dash for over 3 minutes wishing it worked really well, then left it alone for a couple of days. I then tested it before installing the phone holder and it just slid off the dash. I held the phone to the vent again. :-( The manufacturer did their best to fix this, so I'm rechecking.
