The Aspire K3 clearomizer tank is a nice alternative to the popular but more expensive Aspire Nautilus. It is an excellent upgrade over disposable electronic cigarettes that many ex-smokers use.
Unlike the K2 tank that comes with the older 1.6Ω Aspire ET-S BVC coil, the K3 tank uses a 1.8Ω Aspire Nautilus BVC coil which is designed to last longer while creating the purest and cleanest flavors. Nautilus coils are very popular so you can easily find a replacement for your K3 atomizer when it wears out.
Aspire Nautilus coils are made of Kanthal wire vertically arranged with organic cotton wicks for premium flavors. Around the atomizer are four huge holes that draw the juice into the wicks and keep them well saturated. The top of the coil has a silicone stopper that works as spit-back protection while the bottom is threaded so you can easily replace it.
