My first experience was the same as yours. I bought 15 from a supplier because they were on sale for $35 and the
reviews were great, they started out amazing but went down fast. The first ones i got were listed at 2.0 ohm. I went through 12 of these (15 in 7 days), I use the monkeyboxx mod and I would go through 3 carts to drain one 6mil bottle. My first cart form hoosierecigsupply.com is way better, theirs were listed at 1.25. I am now on my second tank using the first cart and it is
vaping like crazy, with great flavor. Anytime i can vape 12 mills of juice from a single cart I am happy. The vapor at 3.7 is the best I have had. Now let me say all of us know that you can get a really good cart and / or atomizer and the next 10 can all be bad, so I caution that I am still on the first cart. I ordered 10 at $2 each. But if the next 9 are 1/2 as good as the first one I am really, really impressed.
