Attention. It is not a suction cup as it says. It is with adhesive plastic which strangely stuck very well after I cleaned the tiles with gasoline. We will see how long they will stay stuck.
I also had a terrible difficulty assembling them. I filed the edges smooth so that the hanging hook could fit

Excellent hook. I am very happy with the purchase. It sticks very well and firmly, you just need to sanitize and dry the surface you will stick it to. It has a suction cup, but essentially it sticks with glue. The 4 stars go to the fact that the assembly was a bit difficult. I had to "scrape" it a bit in order for the hook to "lock" into the rest of the body. Overall, very satisfied though. I would highly recommend it.

Good but this is not a suction cup as it claims, but a sticker. So be careful because it does not have the same margin of error in placement.

Excellent. It sticks strongly, without any issues, and it actually holds the weight it claims. You avoid drilling holes in the walls or door to hang a hook.
I highly recommend it
