Unfortunately, I am someone who sweats A LOT. Being busy going to the gym, everyday movement, I get very warm and my skin doesn't like taking new sensors or just tend to fall off, so I have to strategically time my gym time, showers and going out in general. These Skin Grips have taken all my worries away. They are powerful, they stay on and and most importantly, SWEAT PROOF. Definetly going to be purchasing more in the future 🙌🏻
