I owned an original one back around 2010. I only got rid of it because the surface started to peel off of the pad at the corner. I owned it for a few years. I got a newer one where the edges are stitched so no more fraying. That newer one is ~5 years old and still fine...I use it as a glass coaster now
Due to a new desk I bought, I got the extended one. Unless the stitching is poorly done (it isn't), I expect it to last for a very long time. They are solid albeit pricey.
I can't say I've shared the same experience. Actually the opposite in fact. Never gotten anything sticky to become so stuck to it to give me trouble. Then again, I clean things up like that immediately. With the material, I can often rub something out.
Mine came out good as new out of the gentle cycle (no softener). Feels the same, works the same.
I dunno about others, but Razer rolls them up into the box for distribution. Frankly, even right out of the box I didn't have any difficulties.
