MAKERELE 308 lbs Glass Suction Cups Double Heavy Duty Aluminum Handle Glass Holder Hooks to Lift Large Glass/Dent Puller/Floor Gap Fixer/Tile Suction Cup Lifter/Windows,Mirror,Granite for Moving

I used this as a temporary fix to keeping my car window up (regulator broke) while I save up to fix it. Works great! Has stayed suctions for a couple weeks now.

I bought for an unintended use case: removing gaps in laminate wood flooring. Suction worked well on our boards since they are relatively flat/smooth. The robustness of the thickened aluminum held up well to the impact of a rubber mallet. Closed the gaps with a couple good whacks. Again, not its intended purpose so I would not have rated negatively if it didn’t perform on this task, but I was impressed. Easy to use, great suction, robust.

I had three outdoor porch spot lights that were wedged into the ceiling can 11 feet up. The suction extender did not have the power to unscrew the old bulbs. I measured the bulb width and it was 4.5 inches, exactly what this device was. So I got up on the ladder and used this suction cup which fit exactly and effortlessly unscrewed the light bulb. I used a one inch socket extender in each receptacle and replaced all the bulbs with daylight LED bulbs. Now, it's like the sun is still out when eating at night on the porch. This is a great invention.

OK, I did not use this on glass. I have a security door in my garage which is thick and this door is the entryway to a small crawl space where the water lines for drinking and fire sprinklers enter the home. This door has miserable handles, and you can easily draw blood trying to open when it is closed tight. This suction cup comes to the rescue quite easily and the door now has this suction cup as its door handle. Thanks MAKERELE!

If you can’t actually GET it to stick, which isn’t guaranteed, it doesn’t stay for an extended period of time. But if it’s a short term use, once it’s stuck, it holds decently.

Has a very powerful suction and non slip gloves. For the price you can't do any better.

Worked better than expected. I have two decorative pedestals made of brick and glass block. One glass block in each is " semi" removable to replace light bulb. Not an easy task. This suction cup is a must have for this. Very strong hold.

I put plexiglass in one side of my screened in porch for noise reduction and this devise made it vey easy to handle the plexiglass each time I need to remove it for cleaning. Plexiglass is surprisingly heavy.
