AccEncyc6 Pcs Strong Thickened Sucker Suction Cup Clear PVC Sucker Pads with M6 x 14 Thread Screw Extra Strong Adhesive Glass Suction Holder

Great hold for perfect for my badge window display quality built perfect size for good!

I used these to replace the original suction cups that came with the light bar for my unmarked PD unit. Much better than the originals. I put these on one time; they're still there a week later.

Good suction on a flat surface. Mine are for glass. Did not fall off at car windows at 100 degree F conditions.

I've had these holding up my license plate since last summer and they haven't moved at all. I will say the size is a little sketchy with the license plate but for how much these cost you can't go wrong. You can just pop em on any glass surface and you're ready to go. Thick and super durable.

Great in shower

Great Suction cups. Stainless steel hardware is a plus.Only downside is they are expensive.

According to the information on them, it says they can hold up to 30 lb of weight. It doesn't say whether that's individually or as a group of six, even as a group of six. That's 5 lb a piece. I was hanging a 32-in light bar in my rear window. Weighs just under 5 lb. Fell within 5 minutes. Was really disappointed. Wrote a review saying that they were junk. Change the light bar to the bottom of the window so it has a little bit of other support and it made it through my entire 3-hour route for our route with only one cup coming undone that was this morning. I don't know if I'm going out there. Find all of them undone and it laying in the trunk area or what? I haven't been out there yet so for now they look like they might survive. I might keep them. If it's laying back there then there's a good chance I'll be returning them because they won't hold the weight that they even say they will cuz four of them holding a 5 lb bar is a pound and a quarter a piece when they're supposed to be able to hold 30 pounds either as a group of six or individually but even then a group of four should be able to handle 20. If it's the whole set. Will update later accordinglyUpdate. They held fine until day two. Very first bump. I hit leaving the parking lot. My light bar fell on the cargo bay floor light bar not wired yet. Wanted to test it first before deciding on that mounting position and that mounting setup most likely returning the suction cups or finding another use for them

I have an old hand operated meat slicer from the 1950's. and it's rubber suction cup feet had hardened and cracked. When I turn the hand crank to rotate the slicing blade, the whole slicer would slide all over the countertop. I used these suction cups to replace the feet on the slicer. I had to tap out the holes where the old feet were mounted, but the new suction cups use a widely available 6mm x 1.0 thread, so it was easy to find a thread tap that worked perfectly.Now with these new suction cups installed, the slicer works like it used to over half a century ago. When i place it on the counter, it sticks itself in place and holds securely. It would have been a bit nicer if there was an easy way to get the suction to release, but I didn't think to look for that feature when I bought these. Overall, while it's a bit hard to get my slicer to let go of the counter, it stays where I put it while I'm using it, and that was what I wanted from these suction cups.For what I am doing with them, I don't need the suction cups to hold for long term attachment, as I might if I tried to use them to mount a shower shelf. I can't say how well that would work. But for short term usage - like an hour - they hold very strongly. Overall, they are exactly what I needed.
