Suction Cup Hooks 20pcs 40mm Transparent Sucker Hook for Kitchen Bathroom Door Ceiling Detachable Reusable Suction Hooks No Scratch Waterproof (20) (20pcs)

These are excellent. But like any other sucker there are a couple of things to remember:-1) if the sucker is malformed place it in some hot water, this will soften the rubber and allow the sucker to go back to its proper shape2) Suckers only work on smooth hard surfaces. So no textured or painted surfaces or they wont stick. Some tiles are not perfectly smooth so the grip will be lessened.3) make sure the surface is clean, remove any nicotine, dust or other grime from the surface before use, the cleaner the surface the better they work.4) extremes of temperature WILL weaken the suction power5) always add a bit of moisture to the sucker before applying it, this will enable the sucker to spread properly and adhere wellI used mine to hold up some christmas lights which they did brilliantly on my living room window. I was surprised as the extremes of temperature should have seen these drop after a couple of days, but no, more than a week on and these are still held strong.I really recommend these. Ignore the bad reviews.

They were fit for purpose

Perfect seller thank you 😊

I only been able to use 5 of them as the rest will not work ,suction is very bad ,build quality is very poor, size is okay ,value for money not good.They all weird shape probably because of the packaging

This suction cup is just like any other generic brand; it depends on what you want to hang, but it isn't so strong you need to check regularly.If you moisten or breathe on it first, it stays longer. However, it is not so strong, I have a small crystal hanging on it on a window, and it keeps falling off every week. Another one is hung on the bathroom and it can hold small face wipe towels when they are dry.I think it is still pricey for its quality.

Excellent for Christmas decoration well made strong will be buying more I’d say they med/large size well packed and delivered next day

Brought for window decorations at Christmas did the job perfectly nice size good quality good value for money

Good
