I bought an aspire nautilus mini almost a month ago and have only filled it up twice, and today I went to refill it for a third time and the mouthpiece would not come off.. I had to twist and twist trying to get it, I read some suggestions and loosened the bottom, even was able to take it off in case it was a suction issue, and it still stayed on. I worked and worked to get it off so i could fill the vape and came to find that the coil was stuck in the mouthpiece too tight, even though i know for a fact I didn't tighten it too much when i refilled it last. I twisted to get it off and the glass broke like a very cheap material would, and is now a 35 dollar mistake it seems.. I purchased this item specifically because it was recommended to me as a top brand and really good tank for my itaste mvp. Is there any kind of warranty that would help with this or is this tank just now trash because it wasnt formed properly?
