I have to agree with dime on this. I have the kanger aero mini, kanger aero regular, kanger aero v2, two naultilus full size tanks and the heatvape ceram tank. Last week my silo finally arrived from CA and this tank blows all the other tanks out of the water. To date this is my favorite tank.
Do not get the heatvape ceram, it is a pita for me. Needle fill, there is no way to keep the juice from spilling if you want to pour what is left of your juice in the tank into the bottle without it leaking all over the place. The two tiny o-rings which are under the cap will get lost very easily and the coil itself does not produce the flavor as compared to the bvc coils.
I definitely would recommend the Beyond Vape Silo tank with the Aspire bvc coils. That tank gives better flavor and no matter what airhole size you prefer, it performs and no whistling noise. You can not go wrong with either the silo tank or nautilus tank. But for me the Silo edges over the Nautilus. You also can not beat the look of it. Beautiful design, I am not a manufacturer just a satisfied customer.
