For me, when I sweat the gel loosens up but it dries rock solid with no reduction of the holding power. I would love to be able to have a great 2 week attachment with easy clean up but at this point there is really nothing that is compatible with my body chemistry that allows that. I'm very happy with my gel attachment and I'll continue with it until I can find a better option. For me, the speed and easy of the gel attachment is great. I especially love being able to manipulate the piece for a minute or so when attaching. It makes it SO much easier to get it perfectly aligned every time. With glue or tape it's pretty much one shot. Get it right or start over. That alone makes the gel worth it for me.
