has anyone actually been in the water lets say for like 2-3 hours with the st30 and had no issues with it?
20 min showers are obv not an issue but what about extended time

I went snorkeling in salt water for 1 1/2 hours and had absolutely no problems. The tape held firmly for the rest of the week and I could have gone even longer with it.
Regards,
John

Until ST30 becomes availabe, what is the next best tape to do the same thing with easy cleanup?
Also did you just tape the perimeter? I have never gone under water with my old hairclub unit. I am attaching my new Toplace this weekend.

I think Non-residue tape is also quite good. Easy clean up but it might not be as strong. Perhaps the others can advise?

Ultrahold could be used if you are prepared for a messy cleanuup

john did the tape turn white at all when you were in the water that long?
