They are a cool toy. There is not much practicality to them. $A$$ use would require at least two or extra cylinders. To shoot one, you MUST use a two-handed "choke-up" grip. If you put your off hand on the barrel, you risk a loss of limb. If it chainfired, you would become a SSI candidate. The barrel gets hot also. They aren't too accurate out of the box either. They are a good deal for a conversation piece. If you want it, go for it.
