Logitech V470

A very small and tricky to manuever power switch (on the bottom left). It's about half the size of the one on the V270.

 

The "connect" switch (mid-right) sets the mouse into discoverable mode. It has no physical feedback to let you know that you've pressed it successfully.

 

The laser isn'tas precise as you would think. It's very jumpy from time to time.
