Pisses me off big time when people do this. I now take "As is" to mean "its broken"
I beg to differ, I spent quite a few years as a flea-market trader and "As-is" is something that all ebay auctions should state, even new items as there is no come back no matter what the blurb tells you.
However I agree with "Untested" is something that I wish sellers would drop unless its a bulk purchase.
