I wash my strap every 6 rides.....and I have had my strap now for 3 years. No issues.
I agree, the seal is very tight. Perspiration does not enter the battery area.
My set of screwdrivers are JIS standards. I am not sure if that makes a difference; the ones made by Moody have a very strong tip and a great grip.
