Had a wireless mouse that didn't last very long, it looks as if this is the same I had, but as long as I just type and not use the mouse, I am hoping it will last longer.
He uses it for work and is in love with it!
I have small hands and this mouse works great for me.
The M525 has the left and right rocker on the wheel like this one, but no side buttons.The only niggle I have with this mouse is that the side buttons are both on the left-hand side of the mouse, where my lefty thumb isn't.
(I used to work with M325.).
For a used product, it did what it was supposed to.
It is the mouse.
I tried to use one so-called unifying receiver to transmit the signal from my computer, and, when that arrangement sucked, I tried using both receivers that came with the units, one for each unit.
So now I'm back to using the wired mouse that came with my PC, and, while it doesn't have all the bells & whistles of the M510, it responds better with the basic mouse functions of moving the cursor and right & left clicking.
This is the second mouse I have purchased and both times the scroll button has stuck.
