Hi, I have a Logitech MX DUO 700(mouse and keyboard) and the keyboard recently had an accident.

I have three particular questions:

-May I find a replacement or will it run on a different frequency? (if someone had three in sme room wouldn't they have to be?)

-If not may I use the current transmitter/reciever with a newer model keyboard (3100)

-Can anyone else get Logitech's Global Support Page to work. Or some other relevent page to post this question(s)to them?

P.s Why are these combo's (outdated) so expensive when ordered direct from Logitech.
Oh, I live in Canada.

I think there is a switch to change to a different channel but the distance the devices will work at are small so that usually isn't a problem. I think you may find it cheaper to buy another bundle on sale then to replace just the KB.
