DH needs a new presenter tool, the Logitech R800 seems to have the features he is looking for and I have heard him say Logitech is a good company but just wondering from more technical people if this is a good product?
Features DH wants...
Wireless
Timer with the vibration feature
Long range (this one has like 100 ft)
And the biggest thing needs to work with his Mac

The reviews I read said it did work with a bunch of Macs but they listed different things and I could not quite follow the discussion.

Thanks
