I see more and more of these swiss chees mice, aren't they a mess to keep clean?
I have a mouse like that for ~4 months now, bought it in January and I was wondering the same before but I thought I would give it a try.
To my surprise its not getting that dirty, inside part that is and the outside part is all the same.
Just wipe it every now and then with a sponge and then clean it.
Inside parts so far I managed to clean it with an old smaller brush, its mainly dust that builds up anyway.
Do note that it might be user dependant too, my hands luckily don't sweat that much anymore since I lost weight and I also don't really eat at my PC or even if I do I'm being careful with it.
I needed some time to get used to the much lower weight
'~65g' than my previous mouses but now I'm used to it, I think I'm gonna stay with this design in the future.
