The Elegant 5 Atomizer is great if you want to try a 50/50 or an 80/20 (VG/PG) e-juice or e-liquid. It can cope with either (subject to your battery which should be 1100 mAh minimum). You get the chance to try these liquids without having to pay a fortune for a sub and power pack. The feedback I have recieved tells me it is not so good for normal e-liquids as some other standard atomizers.
The bonus is that it has replacement glass and coils available.
