Pros Light, nice feel for buttons 1,3. Off button is nice feature.
Cons It can't teach myself to click the middle button (the roller) consistently without clicking either left or right by mistake. It is much easier to do left click consistently so I mapped that to do the middle mouse function, which works, but it is simply d

"Very good mouse"on by Padfoot73
Pros Unify technology works really well, the installation is very fast, requires you to download a software to be able to customize the buttons. You can use the mouse perfectly from a great distance.
Cons The middle button click is a little touchy and will often be mistaken for another command, you have to get used to it.
Summary Great mouse for a netbook or laptop users who just go on the internet or use their computer to work.
Pros Not a chunky mouse. Feels very comfortable. The functions are smooth and confident. Does all with ease.
Cons None so far.
Summary I'm not a fan of chunky mice with all sort of buttons and functionality. I want an small ergonomic mouse that I forget is there and does all I want with ease. That's what the 505 does. If you download the software from the Logitech site, you can alter the commands to the mouse. Highly Recommended.
