I have a set of washable bands that I swap out weekly. Cause, ewwwww.
@Cosmichomicide
It wasn't the band. I just installed a new, metal one.
There is a lot of room for "stuff" to collect on the device itself.
Oh yeah - but I clean all my "fingers" electronics at least weekly - phone, keyboard, mouse and Fitbit .
You are clearly a better person than am I.
Do you have a keyboard that is separate from your computer?
OK, so I have 3 keyboards, not including the one I never use on the laptop. Every week they get a superficial cleaning, periodically I pull their little caps off and give them the deep cleaning love and attention they deserve.
Keep in mind that these are my occupational tools (keyboards, mice).
And no, I do not use a KVM. More trouble than it is worth if you have the space to dedicate.
