I've had the Logitech MX Revolution for 2 years now, and it is brilliant, very responsive. I just stick it in the charging dock whenever the battery gets low, and within a few hours its ready to go again. I would certainly recommend it.
I got the Logitech MX Revolution a couple of months back and I absolutely love it, its the best mouse I have owned. If your interested Phil.Smith I wrote a review on it, the review can be found at the below link.
Just bought an Advent Wireless Laser mouse click here= and I'm very pleased with it. There is no delay, lack of sensitivity/response or reliability (signal loss) which used to be associated with wireless products of a few years ago.
It sometimes requires a jab of the reset button to get it connected, but no great issue.
It's not rechargeable - this is just to let you know about the "response"
