Aspire Nautilus 3

Very nice tank. Been using aspire nautilus tanks since they first came out. This is the best one yet. Top fill slide is excellent, very quick and no mess! Push in coil is also very easy to install. As usual the coils last well and produce a good flavour, very slight random leak of juice from air hole is only fault. All the nautilus tanks I've had do this apart from the nautilus GT tank.
My favourite is now the nautilus 3.

Just replaced my old tank with this one, I wasn’t expecting it to be as good as it is, it’s very nice indeed. The slide top for filling is a god send, so much easier than unscrewing the lid off. The amount of vape with a 7 ohm mesh coil is phenomenal. I’ve found the perfect tank as a replacement and I’m very happy.

I had high hopes for this tank, as I already had two Nautilus GTs and one Nautilus GT. However, after having used it for seven months I can only conclude that the GT models work better for me.
1: The slider refill construction sounds good, but in practice it is not as good as the screw-the-top-off refill solution on the GTs. Seeing the small red triangle that shows the position of the slider is difficult in poor light conditions, and the actual slider requires a lot of finger strength. I can manage pushing it, but my wife couldn't.
2: Similarly, the push-in coil construction sounds good, but is in reality quite fiddly, requiring several failed attempts each time I have to change coil. The screw-in coil construction on the GTs is much more straight forward and quicker.
3: While the air hole ring on the GTs steps from one inner hole to the next with clear click sounds, the air hole ring on the Nautilus 3 just slides over the inner holes and you must look to ensure that the two holes are aligned. If not, no air will get through.

So, for all these reasons I will stick with the GTs and have just ordered a new GT - with the 4ml acrylic extension, of course. After more than one year's heavy use, the acrylic extensions for both the regular GT and the mini looks as new. Just as good as glass, but much lighter.
