I work in IT and have considerable experience with technology both consumer and professional.
This mouse is ideal for laptop users whose laptops have built in bluetooth. No dongle or plug in adapter required.
The mouse itself is small (with a footprint just smaller than the size of a credit card, and height around 3cm), and the perfect size for laptop users. It's not too large to be cumbersome but also not too small to render it unusable.
It is a very pleasant black and silver colour, and has a very expensive looking velvetesque finish. Basically the mouse oozes a look and feel of quality.
Also it's a piece of cake to setup and use. The included instructions are easy to follow, and it takes just a few steps to get it up and running, which actually surprised me because usually bluetooth can be a little complicated. The great thing is you don't have to re-establish a link everytime you switch on the PC. Once the link is created it's set. When you switch on the PC, you can use it as is, or if you want to use the mouse, just switch it on using the switch on the underside. The PC automatically detects the bluetooth mouse and re-establishes the connection within seconds. No need for any setup at all. You can use the laptop's own trackpoint or pad at the same as the mouse. Then when you're done, simply switch off the mouse!
The performance is fantastic. Just as good as any wireless mouse I have used in the past. There is a slight hesitancy when using the mouse after a period of inactivity (several minutes), but this is not at all an inconvenience or annoyance.
I can't comment on the battery life yet, but I have been using my mouse all day for several days now with no drop in performance.
Overall a big thumbs up! I just can't believe this little item isn't more widely available. And the little velvet protective bag is a nice touch.
