Like most NC's, it would be nice to know the age of these before you light one. If they are fresh, you might try one ROTT and toss the rest. I don't risk it any more. After I buy these, they go straight to the bottom of the cooler. And stay there for a minimum of six months. With significant time, these can be great. Can be had for good price, just need to assess whether they're worth tying up the space. I'm now working on a box I won in July '10. Had one this weekend and it was superb.
