Review on 📷 Smatree Double Suction Cup Mount: Enhanced Suction Power for GoPro Max/Hero 10/9/8/7/6/5/4/3+/3/2/1/ Hero Session/for DJI OSMO Action Camera (Updated Version) by Michael Domus

I read reviews from customers who had problems with suction cups. I don't know why they had problems other than the fact that the surface they were trying to stick it to wasn't smooth. Personally I would try installing it on a clean windshield before blaming the product. Attached to clean glass, suction cups easily hold a 7kg barbell (as shown). When I pulled on it and tried to loosen the suction cups, I was more concerned about the plastic teeth on the adjustments (which are identical to all other real GoPro adjustments) before the suction cups came loose. All suction cups require a clean, smooth, pristine flat surface and have incredible holding power on a good surface. If I had anything to complain about, it would be the range of motion of the adjustments. I use this Gritech Clamp phone mount to hold my phone in the car and I can't pick it up off my rearview mirror as often as I'd like. However, to mount the camera on the outside of the windshield, it needs to be able to reach any angle forward (or backward if upside down) and have a ball joint range of about +/- 20° from center. If you're going to attach it to fiberglass or anything other than a good windshield, I would suggest tying it not for the suction cups but for the surface of the fiberglass.
