Review on 📱 Cellphone Car Phone Pop Holder Stand with Car Socket Mount for Collapsible Grip/Mount. Versatile Sticky Adhesive for Dashboard, Home Desk, and Wall Use. by Jeff Jordan

I read the reviews before buying. The best advice I've learned is to clean this surface before applying the adhesive and let it sit for 24 hours before attempting to place your phone on it. My phone is heavy and I waited 48 hours (mainly because I forgot I installed it) and I had them on my dashboard for a month and a half with no problems. Don't try to put them on and then use them straight away as they are likely to fall off from what I've read in the reviews.
