I got my seeds from Europe when they first became available for US shipping. Since they were supposed to beat the record, or be close, I always compare peppers to others. The heat was close, but not as hot as red brain strains. Brains have a more long lasting burn where the jigsaws backed off a few minutes earlier. They were about equal to the red lava that Judy had sent me to try. Taste was nothing impressive, but not bad. It's hard to explain, but to me the 7 pot Jonah had a nice red 7 pot taste, but was very bland, just nothing special. Red brain strains have a special taste. Anyway, Jigsaws tasted very plain for me. In the same way, to me, reapers are somewhat plain tasting, where Primos have a really nice special taste, and mine taste about 10% hotter than the reapers. I still have a few jigsaw plants sitting around. It's funny, Fatalii sold seeds with the stipulation that nothing could be sold that came from those seeds, but seeds and plants were really made available for sale months afterwards. That is why I never sold my plants. Anyone who comes out to buy other plants can have one for a present though.
