#4 i use a POWERMATIC electric cigg injector, ive had it for about 5 months with no issues, i'd stronglly suggest you look into getting one of these,,,,vs/....them manual machines, i'll allways have my electric machine, and if it goes down i'll get another one, well worth the money,,, you cant go wrong with the name brand POWERMATIC, #5 I've used the PowerMatic for a few years its bullet proof
