nuoshen 8 PCS Sucker Cups, 41 mm Plastic Sucker Pads Round Threads Suction Cups with knurled nut clear for Daily Hanging Extra Strong Suction Holder

These were the cheapest window suckers and I am always dubious of the cheaper items with few reviews……but I have to say I was super impressed! They arrived on time and in a great plastic protective box, thus keeping them clean and not accumulating dust etc. I bought them to use with my portable solar panels kit that has eyelets. These fit through the eyelets and hold panels well and so useful for attaching to outside ( or inside ) of window or car windscreen. So, great price and really useful plastic storage box……brilliant!

I bought these to hold trade plates onto cars as they are meant to be on the outside of the vehicle. They work absolutely perfectly for this. I tie the plates on as well just in case but so far so good. I am sure they would work for many many things.

The suction on these is decent, but does degrade after prolonged periods. They require re-adjustment every few days or so. I used these suction camps to attach a turtle ramp to the inside of an aquarium, so the conditions weren’t exactly ideal; they did serve their purpose. The build quality of these is good, and they actually do feel of good quality. The thread and nut for these to secure the suction cup is very good, and a very welcome addition given the price. The product comes within a case, which is very cheap feeling, but serves its purpose. These won’t let you down, and I have purchased them repeatedly.

Great suction did the job and got rid of all the discolouration old ones. Yes I would buy again.

Honestly, the quality of the materials is okay. It even comes with a container which I was not aware of. However, Its adhesion is not constant and leaves off the surface after a couple of hours. Definitely, NOT suitable even for the smoothest walls.

Stick really well to smooth surface such as glass, perspex etc.

Bought to attach insulation panels to windows of campervan. Strong. I like the screw on

Not that good if needed to stick to glass as there not soft/flexible enough, well in my opinion anyway,
