Microsoft Surface , BlueTrack, Bluetooth, 4000 fps, Gris

It does exactly what it says on the tin. It has a nice feel to it easy to use.

So comfortable in my hand, the perfect size, I highly recommend this item.

Great little mouse, connected effortlessly to my HP Laptop. I'm very happy with this.

Like the fact this mouse compliments my Surface Book and connects directly with the SB without needing a USB transmitter, so not necessary to have a different mouse for docked & undocked. Less love for the very low form factor, which means that if you have large hands there isn’t a lot to grab hold of. However it still beats using the trackpad in any configuration.

I like the size of this mouse, but it needs an on-off switch. When I put it in a pocket in my back pack, I can see the sensor light stays on. Also, I want a way to turn off the Bluetooth transmission when I am not using the mouse.
