I am also having problems with my Itaste MVP 3.0. I bought my first one back in May it didn't take long for it to start having problems. My first issue came when the ohms readings started jumping all over the place and then my ohms meter would blink like it wasn't making a connection. Then the charge port came lose and it would not charge. My vape store threw it away and gave me a new one and that was in August now it is October and what do you know I start having problems again. The ohms jumping all over the place and the ohms meter blinking. After researching this issue, I figured out it may be a short because it's not making connection so I guess it's shot unless the vape store can fix it. I don't like this model at all having two of them in 6 months! I think they need to improve on their models because lots of people are having the same issue!
