so I got my first box mod, it's a kangertech dripbox. got it at a good price and bought it from someone I could trust. HOWEVER, everything taste like burning ..... I've replaced the batteries, the coil, and instead of using the squonk I used a tank. everything tastes horrible. I've vaped out of a few regulated boxes and the flavor was awesome. I did a test run with the juice I bought today on a regulated box and it was awesome. but it still sucks out of my box. should I trade it for a regulated box or just ger my money back?
