I tried some of these last night, and they're pretty not bad. No, they won't melt your teeth like the ad implies, but they're still pretty good.
These are chunks of real chicken, and not just compressed chicken parts, with a good ratio of breading to meat. When I ate the first one I didn't really get any heat and I thought, "Well these are pretty lame." But a few seconds later I got a really nice burn. I'll order these again.
