Chili lover, I've tried Legend a few times. The first time, two years ago, I got some enormous specimens, one weighed over a pound! But in the last two summers, they've not ripened well at all - I think they need quite a bit of heat. I also found that they are not early, in fact they're later than most others (again, it may be that they need more heat than some). They are supposed to be blight resistant, and were OK the first year, but the blight does eventually get to them. They were expensive seeds, so you've not much to lose by experimenting with your bargain packet.
We're in south Devon, where the summer it tends to be wetter and cooler than in the east. You might get different results where you are.
