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

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.

Great in shower

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

Strongest suction cups I’ve ever bought. Placed them on windshield for emergency lights had to re adjust and they stuck right back on. You have to clean your window first it’s a must for the best adhesion

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

Love it.
