But just
reply with some more info on your keyboard and I'll check it for you.

thanks. it's a Logitech MX 5500



Nice keyboard & your keyboard is very secure to use, if not one of the
best. They handle the encryption at a low level (So its done behind the
scenes with little to no user intervention).

On top of that the max range of your keyboard I think is 30 feet but a
eavesdropper would need to be a lot closer (Logitech claims 3 feet) and
deal with its channel hopping to gain useful data to even attempt to
crack the encryption... and cracking that is no easy task. It just
wouldn't be worth the time / effort.

Heres Logitech's 5 page white-paper on their 'Logitech SecureConnect'
technology if you want a bit more piece of mind. :)
