LEFIMOT Glass Suction Cups Heavy Duty Aluminum Vacuum Handle Glass Holder Hooks to Lift Large Glass/Tile Suction Cup Lifter/Moving Glass/Pad for Lifting/Dent Fixer (2 Pack)

These have excellent suction. I cause this as a replacement freezer drawer handle for my very overpriced Samsung refrigerator. Since the only way to fix the handle was to buy an entire new door, I opted for the handled function cups. To my surprise, they work better than the original part. The surface is curved so it took some finessing to install, but so far so good.

We were installing glass shower doors and these did what they were supposed to do. The doors were very heavy.

Worked pretty good for taking gaps out of laminate flooring, held pretty good on flooring and not smooth

These worked perfectly for carrying and holding our large bathroom wall mirror, to mount back in place after painting.

I was a little skeptical because these were less expensive than some plastic suction cups and there was only one previous review, but I guess you have to start somewhere. I'm happy to say that these performed as expected and arrived in just a few days too. I used them to service a heavy glass sliding door and to realign some laminate flooring tiles which involved pounding on the suction cup handle with a sledge hammer and an intervening block of wood. My only complaint is that there is a strong rubber smell so I'm going to keep them bagged up when not in use.
