Had a slight issue and VGoodiez fixed it, no problem. If I'm going to buy a vape, I'm looking at VGoodiez 1st, every time. They stand by their products and really strive to provide excellent customer service, which is one of the most important things. But back to the device, it works like a charm. I'm mainly using it on the blue setting, which is the lowest. Doing live resin and live hash rosin so far and works like a champ. A big tip that I read about, was to let it heat up, then cut off the device and let it heat up again. Then take your hit. When done this way, you get great clouds from the start. If you only heat it up one time and then hit it, the hit won't be as big to start off with (at least with blue and green). 100% would recommend this device.
