Vacuum Suction Cups for Glass Lifting with Double Handle Locking, Heavy Duty for Glass/ Tiles/ Mirror/ Granite, Gripper Sucker Plate, 1 Pack

The devices worked as expected. There were a couple of slips but those were a result of my haste. When I took the time (like, an extra 4 or 5 seconds to be sure I'd fully seated them) they held very well (in one instance, where I suspended the project so I could get some sleep - 6 or 8 hours - they were still holding when I came back) True, I did place some padding beneath the window to hold it up just in case the cups slipped but they did not slip and the padding was but an abundance of caution.

This is soooo great. We are so pleased and have lifted several glass dresser tops with great ease and we love the product. Thank you so much. Marilee

The motor in my car window broke this is holding my window up and doing a fantastic job of it

Thanks so much it works perfect for what I am using it for.... I use it to hold the ruler for my cutting mat

Works fine for my purpose. I left a piece of glass attached to it and several days later, still tight. Great price.

I bought it to pull dents, it'd work on smaller shallower dents but not large deep dents.

Did not work.

Immediately unsuctioned, even on a clean, flat surface. It was strong for the .2 seconds it worked, though.
