I was really lucky my local vape shop had a Nautilus and I couldn't pass it up. It was their last one and I had read a lot of
reviews including pbusardo's video on it. I love the thing. It is the best tasting mega cloud generating tank ever. I have found a couple of drawbacks to it however. You need to feed it. When it hits just below the 3ml mark you start getting dry hits if you don't keep it level. Basically you need to keep it topped off or perfectly vertical or it starts pulling air into the atomizer chamber. But as long as you keep it topped off over 3ml you are golden. The second big thing is I am scared to death I am going to drop it and watch 40 bucks disintegrate before my eyes. It would have been nice to have incorporated some sort of metal shield or maybe a silicone sleeve for the top of it. Granted it would have detracted from the look but still it would be a cool option to have. I know the first time I bust this tank I am going to cry and then order the stainless steel after market tank for it. I have had it now a little over a week. I just had to replace the coil in it today. The coils are a little pricey @ 4-5 bucks a pop. I am saving my old ones in case I want to try my hand at rebuilding them but eh its 4 bucks. If I wanted to tinker and rebuild my cape all the time I think I would by a Kayfun or a Taifun or some other rebuildable. I haven't tried the kanger aerotank but I want to but my local shop didn't have them yet so far I haven't found any internet site that has the juice I want and an aero available. Before the Nautilus I was using a Smoktech BDC and another BDC that looks awfully like an evod knockoff. I also have a couple Innokin iClear 30 tanks. All of them suck compared to the Nautilus. I just bought an Aspire BDC as a backup and it is pretty nice as well. So I would say my preferences in order would be the Nautilus, Aspire BDC, Innokin iClear30, the evod knockoff, A CE4 that is all stainless and then the Smoktech BDC pretty sure its a Vivo Nova clone but it draws a lot of air and kind of whistles when I draw through it.
If I already had a Kanger Aero I might not want the Nautilus because after dropping 25-30 on it I might be a wee bit upset when I preferred the Nautilus over it lol. But I still want to try the Kanger. I have a funny feeling it may be my third choice but it might take second over the aspire bdc but I have that on a 1000mah evo and is my backup vape and they look good together.
