I have been using them for 6-7 months for the bathroom, for a maximum of 20 minutes, that is, under a gentle water flow they are relatively good! They are easy to install, if they stick properly (without coming off), they can withstand the 20 minutes I mentioned, as long as there is some movement from our part. They are thin enough, which helps to cover curved areas. 3 out of 10 times they tend to come off a little, so it is good for the water not to fall on it with pressure and to check it frequently for any small openings. I had tried Hartmann, MasterAid, and Asepta of this type (waterproof), and for me, they were definitely much worse, as I was wondering why they are called waterproof when they come off in 5 minutes... Of course, one negative aspect is that since they were renamed from Alfagaze to Alfashield, the quality has changed a lot. It was even better back then, and this change has put me in the process of finding new companies again. Maybe I will find the initial durability that only Alfagaze had... Until then, even these ones, with a little more attention, do their job.
