cheap and works well with my computer. running vista and some other bluetooth dongles caused the bsod, this however, worked with everything i tried to connect it to. plug and play so very easy to use too.
i thought it took me a while to adjust to this mouse as i still feel discomfort; i now believe discomfort to be caused by my chair and poor typing habits. i had to use an old style mouse just last week and now i realise how much better this one feels to me, and how it's actually very easy to adjust to this new mouse. The only difficulty i found was clicking too often when picking it up as i was putting pressure in the wrong place. I should add that their support is quick to respond and helpful.
recommended to me by a friend who learned the language at university. i first borrowed the book and decided to buy it as it is a very well written guide, logically ordered and split into lessons. the cd is also very useful.
quick delivery and would buy some other guides if they were cheaper.
