I've tried and I really don't get the snappy - I'm sure it's lovely and all but it seems to be a massive case of emperors new clothes.
The electrical connections with the overly complicated post arrangements are terrible and need almost constant tightening. The reduced chamber uses way to much metal and retains too much heat and there are other "flavour" BF atties that knock it into a cocked hat (eg NoPity)
I'm going to have another clean and reassemble and if it's no better I'm going try to trade it for another NoPity or a predator on UKS.
So far, it's just hype and an atomiser that doesn't perform anything like as well as a £5 derringer clone from GearBest.
