These have to be parked with a humidity control for at least a couple days.
Once I brought the humidity up these burned well. No bad taste. I would have given them four stars but by the time I got them they were quite dry. I used the first one and it was like a forest fire. One week in a sealed jar 69% humidity.  Worked great these things load easy. Very similar to the competitors although these taste a little better got to be honest. And the price isn't nuts. No gripe with the actual product it's the packaging.
Rating: 3 stars
