I tried this once in the hope of finding a good bluetooth mouse. It may work fine in wired mode, but is horrible as a bluetooth mouse. The major problem is it goes into sleep mode after only a couple of seconds and has a long delay to wake up. It is incredibly annoying to use due to this.
I have a more basic Logitech bluetooth mouse that does not have this issue. While it is more basic, it is at least pleasant to use.
