Large But:
- You stink, and not just a little. After using stinks my wrist.
- The surface is uncomfortable at higher room temperature I come sweating because the adhesive and easily tuned firmly.
Small But:
- For my taste, it is a bit too high.
- Blister, non-destructive opening.
Addendum 15.04.2013: 7 months after buying the palm rest still stinks, though not quite as intense, but too intense to still use them for me. I disposed of them today.
