to the mouse pad need not say much, so only the pros / cons:
per:
+ Low
+ Large
Cons:
- It really smells very strongly of chemicals (such as a car tire), which is an evil of it
neutral:
o at the edges of the reference goes relatively fast (due to design)
o comes rolled, thus it must only be something it befor smoothly positioned thereon
Conclusion
If mas it lets air out for a while (I have it on a distant heating for a few days "artificially ventilated"),
then it is OK.
