The new mouse

I’ve just bought a Logitech M205 wireless notebook mouse. Like my older MX650, this mouse uses the 27 MHz spectrum. The wheel doesn’t tilt, but it has a power switch and you can stow the receiver on the underside of the mouse. So far I’m very happy with it as a travel mouse. I’ll keep the MX650 for my regular work desk.

It seems Logitech is going entirely to 2.4 GHz for their mice. This is very disappointing, as the spectrum is so crowded. I’d love to switch, but the interference problems with wifi are horrible. The tiny “unifying receiver” used by their new devices is pretty slick too, but I doubt you could put an effective 27 MHz antenna in such a small dongle. Does anyone make a modern mouse which doesn’t use 2.4 GHz or bluetooth?

I recently switched my primary mouse from a Logitech V450 to a much simpler Logitech RX650. The RX650 is a basic OEM mouse. It is larger than the V450 and doesn’t have the useful space below the mouse to store the compact USB receiver. It only has a range of 1.5m from the receiver, compared to 10m for the V450. So why did I switch? Because the RX650 uses 27 MHz for communication, whereas nearly every other cordless mouse on the market today, including my old V450, uses 2.4 GHz.
