No, I actually am experiencing problems with the sensors. I am quite hairy, plus I sweat a lot (hey stop laughing now...) so the combination of the two factors isn't really helping...
Next sensor, I'll shave the spot to make it adhere more, but I will give a try to
1abRat system as well. Kinesiology tape is a great idea, but what's a skin tac???
Might be the spot I'm using in the arm is not exactly right. I place the sensors almost at the back of the arm because there I'm hairless (well, almost...) but the arm is rounder there and not exactly flat so probably the sensor doesn't "touch" properly in the entirety of its surface.
thanks to all
