Pros: Nice comfortable feel. Smooth tracking and responsive. Purchased for a laptop.
Cons: Defective scroll wheel resulted in return/replacement. Wheel feels like it is out of round and it binds. I have never had this problem with a Logitech mouse and this is about the 20th one that I have purchased. I hope the replacement is better.
Summary: I've only used it for a little bit (less than a day) so I'll give it another week or two before I decide what I'm going to do with this thing.
Pros: None yet.
Cons: Very small, I don't think you understand how small this thing is, at least I didn't. The pictures on the sites and the reviews made this seem like a more normal sized mouse, but it's so small it hurts my hand. And I'm not a 'I need a giant mouse' guy. The tracking on this thing is very very bad. ...
Summary: DO NOT use this for a desktop computer and plug it in at the back. You will never get it out again. The wireless receiver is so small and so poor quality that it will break if you try to pull it out.
Pros: Very precise laser mouse, compact. The mouse itself is ergonomically sound and seems to be well made.
Cons: The small USB receiver you plug into the computer is of very poor quality. Tried to pull it out and it broke. Maybe if it wasn't 1/10th the size of a regular USB flash drive (seriously who needs it that small?) it wouldn't break as easily.
Pros: Very good tracking, my first laser mouse and I am impressed by the accuracy of it when it works, however see below...
Cons: Very poor range - worse than my last mouse that I thought had poor range, you will maybe get 3 to 4 feet away before this mouse doesn't work. It is clearly designed to work right next to a laptop. Wish I had not thrown away the packaging, I would return this in a heartbeat. Now I am just going to...
Summary: I am disappointed with this mouse, it the second I have now purchased of exactly the same brand and type and although it works very well a short distance from the computer, anything medium ranged keeps cutting out making it impossible to work or play with.
Summary: I wanted wireless mice for gaming having been disappointed not with the performance but with the poor lifespan of my Razer Deathadder. Having seen good reviews on here I bought two of these, one for each of our PC's.
Summary: M505 is a decent mouse and I couldn't find any faults with it after buying it. Unfortunately though after about 6 months of usage the mouse developed this very annoying problem. Very often, when you do a single click with a left mouse button, it produces double click.
Summary: Firstly this is a great mouse and worthy of the 5 star reviews on here. Unfortunately one thing not highlighted in the reveiws is just how small this mouse is. For people looking for a full sized mouse (i.e the size of a microsoft intellimouse) I would recommend the Logitech M510 (which in addition...
