Summary: A small mouse, okay when you become familiar with it's size, has on/off switch. Good weight, very well manufactured. Small usb receiver. Price reflects quality, not for everyone, just don't leave it lying around.
Summary: Stylish and good build quality but temperamental on a lot of surfaces. Hard to find a surface where this mouse is accurate and the cursor doesn't jump around. Having to purchase new mouse as this one isn't great on a wrist supporting mouse mat I recently bought. Otherwise a slick mouse.
Summary: I use this mouse at work and it proves to unresponsive the majority of the time. The mouse glitches regularly making it hard to create designs. When starting up my work pc the mouse will die regularly until I hard reset my system a fair few times.
Summary: This mouse is a good size, has great connectivity (no lag) with my laptop and has a handy store within the mouse for the usb antenna attachment. Another bonus is the usb attachment is very small so if you do forget to take it out of your laptop before you pack it away for your commute it's unlikely...
