Review on Logitech M510 Blue Wireless Mouse with USB 🖱️ Unifying Receiver - Comfortable Shape, Back/Forward Buttons and Side-to-Side Scrolling by Ngo Quang Cuong  (Cn ᠌

I bought this miracle in the hope of getting convenience and quality work for such a price. Already when unpacking, it seemed strange that it had 2 heavy AA batteries, when all other similar devices have light AAA batteries. Further more. The hand lies very uncomfortable due to the symmetrical shape. Essentially, the little finger and ring finger are just dangling in the air. The side buttons stick out, have a large stroke and are pressed with a rather loud sound. But still, everything that was listed before this is nonsense compared to the main drawback - positioning. It's just HORRIBLE! At first I thought that it was the surface (an ordinary laser mouse pad), but changing the pad and trying work on completely different surfaces did not give a significant improvement. I downloaded the software from the manufacturer's website - it also did not give anything, and besides, the software is terribly inconvenient. As a result, he spat and threw the mouse into the box, where this rubbish belongs.
