Update from my review, after trying on to my original Nautilus, it fits like a glove with no leaks, amazing for its price.

First of all its value for what you pay for and its cheap. It has some rust stains in the inner lining when I got mine. Therefore it got me thinking "Is this high grade stainless steel?" I am not sure about that. Inside the wells just after the threads ended at the bottom has metal shavings that are still sticking to the tank itself. Had to use a screwdriver to get rid of the shavings then sand it down a little. But the inside walls of the tank is smooth, no problems. Threads are not that super friendly..has to turn slowly and make sure you don't cross threads when you are screwing down. Will apply some silicone grease to the threads before I screw down next time. Have not tried this on to my Original Nautilus yet, but will try soon to see if it fits or not. It does fit with the Nautilus sold here (I bought one from here as well) but will cross threads if you are not careful enough, but it FITS. It does carry the Aspire wordings on the tank. Overall its still value for money when you are paying 3 times the lower price...so it's ok with me.

Good quality and very cheap. Can connect to all phones and fit snugly and not loose. If anyone that has a problem of a micro usb connector whereby the head is too short this will solve your problem. The extended head on the micro usb is long enough to fit in and not loose whereby it will come off accidentally and not charge your phone. Very satisfied with this product.

Basically vapor production is good. Throat hit is there. But he juice is a little too sweet and not enough chocolaty taste. A stronger cocoa taste will make this good.

One piece can last 3 - 4 weeks. Every second refill will wash & dry burn. Comes back to life. Good vapor production. Threads will last if apply a little of silicone grease. Very minimal leaks at 510 connection. Sometimes will have dry hits at 11 watts. Solid construction.
