Power Lock Suction Cup Hooks (4-Pack), Each One With 20 lb Capacity (Yellow), by Lynnwang Design

They break easily

I was skeptical at first but these have blown away my doubts. I stuck a dozen to the tile backsplash in my kitchen with the intention of hanging colorful fiestaware mugs up. My dishes have yet to arrive but I've tested out their staying power with large stainless steel water bottles and thermos' with none dropping or loosening at all and this over the last month. You can grab the hook and apply pressure downward and feel that they aren't going anywhere. I did rub down the tiles with rubbing alcohol beforehand to make sure no dust or anything effected their suction. I will upload pictures if my fiestaware ever arrives (thanks Kohls).If you found my review helpful please let me know! There's a place to answer under my review. Feel free to also ask any questions.

The only place these stick for any length of time is glass. Otherwise - be prepared for the late night crash as whatever you hung on them falls! They also come in the worst, least inconspicuous colors. I was willing to tolerate that if they worked, sadly they do not.

These hooks work! I made a large, heavy wreath and could not get the conventional suction cups to hold it on my front door. The last attempt was two hooks at the top and two at the bottom. After the wreath falling off the door a half dozen times, I knew I needed a different (not MORE) suction cup hook. This one has held up for months. I gave one to my mom, and she loves hers too. Great price to boot.

Very strong hooks! I have one of those automatic shower-cleaning bottles hanging from this, with the suction part on shower tiles. It's been up now for over a month and looks like it'll stay until I take it down.

Have just played with them so far but they seem very strong. The plastic seems to be good quality and should last if treated properly. Would buy again.

Works great but the are must be cleaned well or they won't stick.

My wife is very happy with these hooks, so I am happy.
