Hi I'm new to vaping. The local vape shop recommended the XROS 2 as my first vape. I really enjoyed using the unit, but when it come time to change the POD I started to have problems with it. I installed the pod, filled it, and let it sit for 5 minutes, just as the shop keep showed me, but when I went to use it, I got an awful spitback. I removed the POD to find the juice was also below the POD in the unit. I inspected the pod for cracks and other damage and couldn't find any. I then placed the POD that I was previously using back into the unit, just to see if it was the new POD but to my surprise the previous POD was also giving out a nasty spitback. I'm not sure what else to do to fix the issue. I made sure the battery was charged, used the appropriate amount of liquid but it's still giving the terrible spitback. Can someone please help.
