New Karakal Super PU DUO grips?

[bethc]

Has anyone tried these, have spotted them on ebay, but don't know whether they are any good or not. The seller says they are new in?

Hi, have no personal experience of these grips, but had heard of them, but the only info I ever found was through the karakal site www.karakal.co.uk. Its the usual speel of "wow, look at our technology", but it does look alright.
