I saw these on special offer in my local supermarket for £6, so I bought one.
It took me just a couple of minutes to unpack the mouse, USB dongle and batteries, then I followed the instructions in the manual.
When I plugged the dongle into my laptop's USB port, Windows XP recognised it and installed drivers for it within a minute and it was ready to use: I've got the MouseWorks software from Kensington to give me better control, but the standard XP driver works fine as it is.
This is a very responsive mouse, it's small enough to fit in the palm of my hand, it moves very nicely, especially over something like a white sheet of paper (or optical mouse pad), and I just really like using it.
Like with other mice, you can still use your laptop's built-in trackpad (or trackpoint) device instead of the PocketMouse without having to fiddle around with disabling and enabling different pointing devices.
There's an on/off switch on the underside that you can use to turn it off if you don't need to use it for a long time, and a built-on inactivity timer that switches the mouse off after a period.
You can use the scroll wheel to wake the mouse up again if the timer switches it off.
A great buy for £6, I've yet to find any flaws with it, and I like it so much that when I told a friend about it, he asked me to get one for him, and he's impressed with it too - even Windows 2000 will recognise it automatically.
I would recommend reading the enclosed manual before setting up the mouse, as they include tips on the best surfaces to use it on and you need to press a connect button on the dongle when you insert or change the batteries, but that's fair enough to me.
The Kensington PocketMouse Wireless Mini is the perfect device for busy travelers. QuickRF wireless means working without hesitation, delay or interference. A battery-saving on-off switch saves time and expensive replacement batteries. DiamondEye optical technology provides precise tracking on virtually any surface so you can work anywhere. And with the ultra-compact design and travel bag, there's just one very small thing to carry!
