Summary: Bluetooth range is not good. If there is ANYTHING in the way, you will lose signal, and sometime it won't come back on it's own and you have to reset the mouse to use it again. When the computer comes back from sleeping it also takes forever to get Bluetooth signal again. Batter life is also not good. The only redeeming factor is the multifunction buttons, which are very useful. Recently got the HP H3T51AA which is infinitely better.
Summary: I love the feel of it as a mouse. It's solid and accurate. There are great little functions too - the laser, changing slides, zooms, changing back to mouse mode... Go straight to the current version of software off the internet. All CD's provided in the package are obsolete - I don't know why manufacturers still include them. I'm shocked by the price though...I think I paid around 70 or 80 bucks for the one I own now. They seem to last 2-3 years before they get buggy.
Summary: I give a great deal of PPT presentations (approx. 100/year) and this mouse is amazing! I typically interact with my audience (e.g. walk the conference room, that is) and its BT connection has yet to drop, even when I'm more than fifty feet from my computer... I can even use this mouse sans the accompanying BT transceiver. In light of it's compact size, this mouse/buttons are responsive to my commands.
Summary: After doing lot of research I narrowed down to this mouse with the following criteria I had. 1. It should have more than 3 buttons. The forth button on the mac would be used for expose. 2. It should not be notebook mouse, i.e. small and tiny. 3. It should be wireless and use Bluetooth and not a usb adapter, because there are only 2 usb ports on mac pro. So I can't block one perceptually. Most of the good wireless mice are not Bluetooth or they were small ins size.
Summary: I have used this product for quite a long time. I'm sure this review is far too late to help anyone, but here it is anway. This was never a very good mouse. It has a large number of bells and whistles but they never quite work right. - The battery life is very poor. It lasts about 3-6 weeks and those weeks come up quick when you only use the mouse occasionally. - The bluetooth connection range is very poor which is very frustrating during presentations.
