I installed the product in two showers and I am very satisfied for a week now. I see many negative comments about it coming off.
1st, the surfaces need to be cleaned well with alcohol to avoid dust and grease.
2nd, the surfaces need a little warming with a hairdryer for the adhesive to soften and stick, and once installed, the entire tape needs to be warmed again and pressed well for the adhesive to grip.
The tiles and porcelain are cold objects and harden the glue, preventing it from spreading and gripping, which is why warming is necessary.

Honestly, I haven't encountered any problems so far.

My first thought was "well, they have no shame selling such a product." As a material, it is good, it doesn't cut easily, but the glue is terrible!!! The next day, it had come off from everywhere...
