As often when it is sales period, Logitech products are subject to significant reductions. This is the case of MX Master (1st generation), a high-end wireless mouse sold for € 59 instead of € 89. This mouse has two wheels, one of which is under the thumb, as well as a set of buttons. It can be connected via Bluetooth or via a dongle and its battery is recharged with a Micro-USB cable.
More compact but still high-end, the MX Anywhere 2 is on sale at € 44.99 instead of € 79. No wheel under the thumb, but two buttons, and it recharges in USB-C. If you don’t need as many buttons, the small M220, which has the advantage of being ambidextrous, is almost half the price at € 13.99.
For gamers, the Logitech G203 wired mouse is € 25.99 (- 35%) and the more advanced G502 is € 39.99 (- 35%).
