Bluetooth Connectivity, plenty of buttons, good weight and size, quick to connect

Buttons aren't programmable!

This mouse is just awesome for travel. Small, acurate, bluetooth enabled, batery last a long time, as I write this I've used it for 4 weeks with the initial batteries.

havent found cons yet.

I love the fact that all i have to do is turn it on and it automatically signs in for me, no messy wires, nothing special to figure out, just follow the instruction card and install should be fine

battery life

Great mouse! Started using it with travel and now will also replace mouse at docking station.

Had some difficulty keeping connection initially on Vista, but after first couple attempts have not had problem since.

very good 5 second hookup very responsive. love it

none that i can find

True that connecting is an issue with my 1420. I don't know if its a driver problem but no available drivers seem to always connect without fail perfectly 100% of the time. Something about coming out of sleep or if the lid is closed it takes a bit to...

It's Bluetooth! Yeah!

This mouse is too heavy and too large for a person who does not have a large hand. It's like working out with a hand weight!

Excellent, small, and very useful for a laptop

Have had some difficulty on my computer between the Bluetooth and Vista, but it's only a minor annoyance and not technically a problem with the mouse. The mouse buttons occasionally activate without being pressed.

Nice feel and good precision. Five button mouse with scroll is great for web navigation.

Bluetooth has a limited range that can be a problem when using this mouse for presentations so it is not for everyone. The next generation of bluetooth should extend the range.

Nice size, works great.
