These came in fast and in excellent condition. There was no warping and the material is sturdy and slightly rigid.I used them to superglue fruit shaped feeders to. These are being used as frog cups for baby White’s Tree Frogs and it’s stinkin adorable.The suction cups have held on and there has been no movement or popping off. They are great!

did not work for me

Ordered this on July 31... great Amazon shipping to it to my door around Aug 2. Today is Aug 26 as I write this review.Not even a month of use in my aquarium and they are failing miserably. They do not retain shape or suction. All my things started falling to the button or floating... so I checked the suction cups and sure enough... they are now stuck in a "squished" state with no more grip power. Product clearly does not perform as promised, not even after a few weeks of use.See pictures attached. The clear nice looking one is "new" (not used) next to 2 that I've used for a few weeks only and you can see they are rigid and flat with no more grip power.DO NOT BUY. You have been advised, at least from my own personal experience :)

I purchased these on March 6, 2022. I had to install a solar panel on my car to keep it charged while parked. Before installation, I cleaned both surfaces. I attached all the suction cups to the inside of my hatchback window and the other sides to my solar panel. After two months, it fell off the window, most of the suction cups stayed on the window and one fell with the solar panel. All the other suction cups fell off the window into my hand as soon as I touched them.I will give these the benefit of the doubt. First, they were attached to a hatch back that is operated several times a week and the closing of the hatch has a significant impact on the hardware. Second, they were exposed to hot and cold temperatures every day, which could lead to compromise. Thirdly, they were exposed to moisture, which is quite common in my area.Coming from a different perspective: if these suction cups were used in a controlled or monitored condition, there's a likely chance that they would remain on the glass and not fall off; say, for instance, a living room window facing north mounted on a triple or double-pane window in a room that is at 70 degrees year round, and the humidity is at around 50%. In that case, these suction cups may just work perfectly fine, rather than my situation which consist of concussive impact, fluctuating temperatures and humidity.

I have an EZ Pass that I carry with me (I live in Oregon) and use when I am flying to the East coast. I glued a small piece of thin plastic to the back of the EZ Pass because to use these suction cups the surface MUST be glass-like-- NO texture! Now the suction cups work great and I can move the pass from rental car to rental car for all the tolls there.

Bought these in hopes to put under my toddler plates so it stays in place and prevents from her spilling it on the floor, but these little things have 0 suction, maybe to support a glass table top or something like that it could work but it doesn’t work for most things. I’ve tried using with different things light, heavy etc.

Ok for the suction, didn't work too well for the item I was using it for but that could be the surface problem.
