I bought an eGo AIO Pro C two weeks ago and it's been furiously spitting hot juice and gurgling since day one. I've attempted numerous times to contact Joyetech customer service and have never heard back. Everyone has a trick they use to keep their Joyetech machine from spitting and gurgling but let's face it we shouldn't need to "trick" our machine to not do something it shouldn't be doing anyway. Fed up, I went out last week and bought a Kangertech Subvod Mega TC and it's been great. You prime the coil, screw the tank in place, fill her up and you're good to go, no gurgling no hot juice exploding into your face, none of that ever, no tricks required. Nonetheless it would be nice if Joyetech would provide some customer satisfaction. I guess that's just a pipe-dream. So the review is this: If you're high and you have a lot of money for a cheesy light show this is the machine for you. If you're looking for a quality machine that produces a great vape at a reasonable price and is backed by a reputable company that cares about customer satisfaction, buy a Kanger.
