You get what you pay for when it comes to this product. If you don't want to spend upwards of £10 on a fabric MAT, then you should get this. It is exceedingly cheep, and does the job - but it is definitely not a perfect product. It has problems sticking to the desk (easily remedied with various household items... use your imagination), and it tends to curl up a bit on the corners when you first get it - but tends to stop after the first couple of weeks of use (strange).
Basically, you're getting a mouse mat that actually works for less than... £2 at the time of writing - so, hell, what is holding you back?
