Bought this in early 2006, had been wanting a low-priced alternative to struggling to draw with a finger pad..
Tesco; £20 was the cheapest I've seen anywhere and snapped it up.
After the initial excitement wore off I forgot about it and its only recently (Oct 2006) that I've got the thing out and decided to put it to some serious use. Compared with the £200+ professional products it probably doesn't compare, but for the home user, just messing with a bit of cutting pasting or doing the odd sketch it is amazing.
The pressure you need to put on to register is something that takes some getting used to, at first you feel as if you're learning to write again. After this you begin to get a real feel for the pressure you can use. The pen feels nice and solid without being heavy.
