Well received. That's what I wanted. Tested on a garden shed roof. Easy installation. Five cms is a bit tight. You have to aim. The glue is effective but doesn't like low temperatures. It becomes brittle. Let's see how it holds up over time. THANKS

I don't know what other people got, but I can't confirm that it's supposed to be watertight and can't be removed. It's just a normal adhesive tape, nothing more, nothing less. You can save your money.

The roll sticks on both sides from the outside. Anything cut off doesn't stick at all but crumbles from the bottom.
