Review on 🖱️ Renewed Logitech M705 Wireless Marathon Mouse: 3-Year Battery & Hyper-Fast Scrolling in Ergonomic Black Design for PC/Laptop with Unifying Receiver by Kero Kero ᠌

I've been using it since 2022 and have had no complaints since. Bought as a bundle with MK700 keyboard. At first it seemed cumbersome, but later proved to be very convenient to use. The batteries last for a long time, but there is a caveat: the batteries are connected in parallel. If one element "lags behind" and gives a current leakage, then a skew will occur and the second serviceable element will drive the current through the faulty one. As a result, electrolyte leakage is possible, as it happened to me, since it did not affect the printed circuit board and managed to clean the contacts. Therefore, it is necessary to carefully monitor the state of the elements, it is advisable not to "finish off" them to zero and change them in a timely manner.
