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!

Best suction cups ever

It was greatBut it wasn’t put through my letterboxI collected it off the driver at my door

Does they job.

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

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.

I had high hopes as others said they were good and had strong suction. I tried several times to get these to stick to a tiled wall to hold a soap dish, not exactly heavy! Everytime it has fallen off after a short time...
