So I'm relatively new to the vaping community but my first vape pen was stolen so I figured I'd just buy and inexpensive mod now and see how I like it. With the pen I only used the juice Starship by Space Jam and I loved it. Then I switched to the istick and it worked fine for about a week but then it started tasting burnt and just bad. I was told to but a nickel coil which I did and replace with no problem but there's still that burnt taste and feeling. I ran out of starship so I figured I'd try a menthol flavor made by diamond vapor because I heard it was really good....and I cleaned everything out and it still tasted burnt and terrible...does anybody know anything I could do to fix this because I don't want to have to buy a new one. Thanks in advance.
