they are a real crapshoot, when they are on, they are phenominal, when they aren't its like smoking windex. i've had very good and bad and they are worth the wait even if you do get some that are sick.
Got a box i've been sittin on for 2 years +. every time I want to break down and open the box i get one in a trade or a PIF and I get my fix to last another while. I hope that keeps up for another 5 years...lol
