I just got a ITaste MVP with the I clear 30. I like it I also ordered the backwoods brew espresso e juice for it its really good in the I clear 30! but I had bought a cheap flavor from the gas station called berry blast because I was under the impression the espresso juice would come in the mail a few days later. the espresso came on the same day as my mvp so i vaped it and enjoyed it but I got curious about the berry stuff. so I bought what I think is a ce-4 tank from a head shop and poured it in. IT WAS NASTY. It tasted like it was burning too. so I did a little googling and found that you have to remove a little silicone from the seal under the tip. after doing this the burning taste went away. but prior to this u dumped the berry stuff out rinced the tank and wick and poured in my espresso. the flavors in that tank still taste mixed to me. only issue now is that I noticed today that one of them is leaking from the bottom and I don't know witch one. there is a small amount of fluid on the battery connection part of my mvp. is this a common issue? will this damage my mvp?
