Icemat changed their name to Steelseries and they then made the Experience I-2, which was basically an Icemat Gen 2 with a Steelseries logo, but that was years ago. They've been out of production for ages now

think I got mine just as the name change was going on, at a guess they've not been made for about 5-6 years.
Like you say, they're so long lasting, clean up great with ordinary polish, and there's just nothing out there that is a decent replacement.
Nice to see another Icemat user though, we seem to be quite few and far between!
