From a practical point of view, I "saw her": I had an old mouse pad which I was very attached - personalized gift for a friend who is not - plasticised, damaged, wrinkled and my mini Mouse infrared played mad, jerking all over the place, bumping the folds, the cursor doing what he pleased ... To go on I would have tendinitis and become as mad as her!
With this mat, mouse adheres well but also glides smoothly, FINALLY, she no longer dances the salsa of the devil !!! Heaven, it's good! The 3mm thick are a plus for me. If one of our actions is unclear, it is not "landed" hand doing tricks to hold on ...
Value, I do not think we could do better.
Here is a small accessory that, in my view, has all the qualities and that I can not very strongly advise.
A word ...
When you can make life easier, if only a little bit and with so little and spending, better not hesitate.
