Um, bad. Strange ergonomics. LONG heavy trigger. Seem to recall it was unreliable because they changed something about the feed ramp (or something). Low overall quality, so when they first came out I saw lots of people bringing them back into the store or asking around for spare parts and other fixes.
Just generally seemed to be a sort of junky, poorly conceived and designed gun. Then they just disappeared. Not just no longer made, but no one wanted one used either, so apparently all are in the back of safes or the bottom of the ocean. Haven't seen one for years.
Not as bad as the AA2000. That was neat handling I thought, but blasphemously bad mechanical design and quality. Shocking. These two pistols, and some QC issues I have seen with AR-15s always left me leery of Colt in general.
