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

I work security and got these suctions to put on top of my tesla model 3 performance. They suction super well that I have gone 80mph and they stayed on and shows no signs of getting loose. Definately a sturdy suction and easy to install.

Great suction and easy to work with

I used these for my floating shelves in my bathroom. I’ve had them up for over a month and they don’t budge. I really wish I would have gotten them sooner. Very sturdy, high performing. Perfect for organizing cosmetics.

Very similar to the DANXQ ($2.50 ea), both 55mm diameter with a M6 bolt & nut (basically a 1/4-20).I hung a 5 lb. weight using a small chain from a metal ceiling plate (not glass smooth) using 1 suction cup. AccEncyc held for 139 mins. - DANXQ for over 3 hours.The AccEncyc are good, but the DANXQ appear better and seem a little more heavy-duty. The AccEncyc have stainless steel hardware, the DANXQ do not. There are also other comments that the DANXQ are not UV resistant for outdoor use. Either will serve my purpose of attaching a tarp to the side of a teardrop camper using 5 suction cups.3 AccEncyc did hold a 6 x 8 tarp to the side of the camper for several hours on a windy day with no problem. I did not have the DANXQ at the time.NOTE: Results are best of 3 test. The metal surface and the “sucker” were cleaned with a damp microfiber cloth before each test. There was obvious improvement in performance with each test cycle, probably due to “sucker” oil (plasticizer) reduction.
