Am not an expert, but I find the Zephyrus to be good. Using it at 20 watts on an IPV4s mod, 26g Kenthal wire (8 times round a 2mm mandrel; have been advised to go for 7 rounds but i haven't tried that yet) and Kendo cotton for wick. It has never leaked, no dry hits and I like the ease of filling. The spare parts included with it (spare glass tank, grommet/multi colored gaskets etc) are also a nice touch.

About ease of recoiling and cloud production, the best way to answer you is this video (very worth watching...I learned how to recoil from it):

I wish to try making my own e-juice. Can anyone please recommend me a good supplier of PG, PV, menthol flavoring etc? Am looking to buy several liters. Thanks!

A quarter way through my 3rd tank of Red Bully-cious, got a burnt taste. Opened up the tank and found the wick and coil to be black. Scrubbed coil and re-wicked. Didn't want to waste the juice, so I mixed it at 1/4 and 1/3rd tank with other juices, no problem so far. Will not buy it again.

Congrats!! Be strong...u can do it!
