4.5" Car Camera Mounting Kit Pump Vacuum Suction Cup Mount, Professional Camcorder Vehicle Holder w/ 360° Panorama Ball Head and 180°, DSLR Camera Video Stabilizer Car Sucker Cup Holder (4.5")

Good product, fast delivery, works well.

Wouldn't be surprised if you could use these to climb a glass building. The hold is extremely strong. Had it on my sunroof and the sunroof itself was starting to lift and the go pro was still sitting firm on the mount

Good suction while it lasts, but does tend to slowly lose suction after a few hours. I think the longest it stayed up was about 20 hours. I use it all the time though and just keep an eye out for the red line on the pressure button.

This item worked extremely well I never had it fall off and that was doing 70+mph. it was beyond easy to use especially with the size of it.

The media could not be loaded. The suction cup it’s self is mint but the mounting hardware seems a tad cheap, stay tuned for some rollers my friends and I are gonna take

Suction cup works very good. It is strong, solid, and easy to use.The gimbal was badly threaded on top and bottom because I couldn’t even start to thread them on with any of my other items. Luckily I had the right tap, and the right die to make everything work smoothly. However the ball joint still doesn’t work very good. I used this to hold a small phone on my 4x4 and it kept rotating. It wasn’t the stud though, it was the ball itself. I kept tightening the wing nut to no avail. Where the ball base mounts to the female threaded base it doesn’t sit flush and allows it to wobble and rotate. I may just buy a better ball base.

Put two of these on a drift car that got thrown around for two days and it was completely fine

Some of mine worked, some didn’t hold suction. But now unless I drive across town to a Whole Foods I get charged for a UPS return, so returning malfunctioning product costs ME MONEY. Terrible product/seller.
