The only reason I have not given 4 x 5 stars is due to the fact that I have only used the single coil, so I checked out the eleaf web site and found out that there's 4 different coils available for this little beast. 1, 2, 3 and 4 coil versions. Apparently the 3 and 4 coil versions give the best flavour and cloud production so I hope that they will be available through Supervapestore.com.au soon!.
This tank comes with spare o-rings, and 2 coils (HW1 and HW2). The drip tip is a little too short for my liking as it tends to get warm and there's a chance of the liquid getting through.
The slide open top fill on this unit is awesome as you don't need to take the tank off the mod.
Definately worth buying this tank, and I'm very happy I got it.
