Query: Excellent wrist rest, poor quality

PROS:-The gel is the most comfortable feel I've used.-The nylon material is non-abrasive and comfortable for long periods of use-Wrist rest is heavy and will stay put-Cleaning up the goopy gel that leaks out is sticky, but leaves no residue on fingersCONS:I've gone through 3 of these wrist rests in the last couple of years. The nylon material keeps separating from the base and then the gel is squeezed out onto the keyboard/desk/etc. I've replaced it with a new one when I get tired of cleaning it up. The latest one I bought didn't last more than 5 months before the material separated again. I'll be replacing it with a different brand.
