I have had 1 nautilus, 2 aerotanks and most recently the aerotank v2 with the v2 atomizer heads. My problem with the nautlius was constant leaking. My main problem with the aerotanks is dry hits. I'm almost positive it's mainly the coil heads causing the dry hits. It is my understanding that it is a known thing that the replacement coil heads have a high failure rate? I find this kind of unacceptable. I am growing tired of the inconsistency of this ..... Some days are great and some days it seems as if i have nothing but problems and it does nothing but drive me to a real cigarette. If someone can please recommend a tank or any ....ing thing that is consistent and reliable that would be great!!!!! I don't feel like taking the time to learn about rebuilding. I'm willing to fork out the cash. It doesn't necessarily have to be a clearo, it can be anything! please help.
