Summary: It works well, straight out of the packet (once you've got into it) but I wish it was a bit bigger. I have long fingers so it's not as comfortable to use as my last mouse, which was 2cm longer. (They don't make my old one any more or I would have repurchased it) The settings are easy to change, which is great but I haven't yet managed to find the setting I want for gentle scrolling - I keep finding myself at the bottom of the page/document instead of the next bit down.
Summary: The colours were red and yellow, not pink and purple. Not what I thought or liked, so I had to send it back. Otherwise a lovely item. This range of mice/mouses? is well-designed, with a smooth movement. You only have to plug the transceiver back into the base when not in use or not left in the machine. Much better than having to remove the cover to store the transceiver. If you only use one mouse I'd advise you to leave it plugged into the machine.
Summary: The mouse arrived promptly but was faulty. It felt very "plastic" and would have been just OK. Returned and money refunded by Amazon within a couple of days. Well done Amazon, good service as ever. Eventually bought Hewlett Packard which is excellent.
Summary: Pro: I bought this because I wanted to be able to use it on any surface, and that's true. Con1:It chews through batteries at an alarming rate. An auto sleep function would have been nice and I'll definitely be looking for that feature if I ever replace it. Con2:The black that is visible in the picture on the sides of the mouse are vinyl and after three months of use one side has already parted company with the mouse and is loose.
