Great simple device. Well made and well priced from vaping101. Build correct and this hits well. Probably not as hard as a mech but for what it is, it's up there. Cant see a reason to buy a proper mech over this semi mech, prefer the safety this gives me. After all I vape to quit, not to get things explode or have you pay attention consistently to ensure it doesn't. This Semi Mech fits the bill perfectly as long as you got experience of building and ohms law.
