I got them to protect incisions from surgery during shower time and water was passing through as normal. I was putting extra tape to keep the dressing in place....

If you want absolute waterproofing, you put this on and then a Tegaderm sticker on top. One week after surgery, I swam in the sea for hours every day this way.

They indeed do exactly what they promise. They are waterproof, stay put in the water, and remain in place for as long as you have applied them to the skin. I have tested them while washing and in the shower, but not yet in the sea or the pool.

And water has passed through me, but also when I remove it, my skin literally comes off with it. I don't know if this has happened to anyone else, but its sticker has really injured me.

I wanted them for the Libre, what else.
Unique. Not just waterproof. No air passed through.
About 1 hour in the water.
It had a trapped air bubble inside that never went away.
HOWEVER...
1) without cleaning with alcohol, it peels off like the cheapest ones.
2) it is not hypoallergenic. It may cause pimples. Don't leave it there all day...

Really a good product. It sticks very well and stays in place for at least 2 weeks. It has not been used in water so I cannot evaluate it, and it has also not been tested in intense sports conditions. For this reason, I give it 4 stars. 15/12/2022 I come back with 5 stars after testing it in sports conditions

I have not tried any other brand. These, however, do their job very well. In the bathroom where I tried them, no water passed through. I will try them in swimming and we will see. They are worth their money.
One tip is to clean the surrounding area well with alcohol so that it sticks better.
It was also tested in the sea and indeed no water passed through. However, the area where the application will be made must be clean, otherwise it will not be waterproof.

Excellent product. My wife uses it to protect a sensor she wears on her arm so that it doesn't come off and also to keep it from getting wet. I highly recommend it

It is the best in its category, however, it is not completely waterproof like none of the others we have tried.

I bought the 10x15. Very good. It is not one of those that come off. If you apply it correctly, they might stay on you forever. Nice texture. Maybe a little expensive, that's why 4 stars.

It sticks perfectly to the skin, you first remove the sticker, stick it to the skin, and then remove the paper on top.
