I own several and only now use the mini nautilus when I have to for stealth work vaping. If allowed to vape my choice all day everyday I would not touch anything Aspire makes thus far since I have found love in other setups. I write this because out of my obscene quiver, I own at least 5 Aspire products and looking through each page of threads at least 1/4 relate to Aspire topics. They own perhaps the biggest part of the clearo market and they are rock solid for what they do. Applause to these innovative folks. I cant wait to yet again give them my hard earned cash for a top fill subohm tank that can handle my needs. Lets do it Aspire.
