The 'bling' thing seems a bit overhyped too; mine gets dropped frequently and does not get polished; still works great but isn't really equivalent to jewellery.
The two features I really like about it are the telescoping section - you can use many different combos of batteries in it, and it will change its length to accommodate them. The other thing is the collector tank - this is a gasketted catch tank that surrounds the base of the 510 cartomizer (or atty). If you overdrip on your atty or carto, extra juice goes in the catch tank, and not in the mod or on your hands. The collector tank also has a gasketted ring on it allowing you to change the amount of air drawn in with each puff - if you think a particular carto or atty is "too airy" you can choke down the airflow using the collector tank ring, or open it wider to allow more air to pass in.
An eGo-T atty and tank works on it as well if you get the eGo-T 510 extender bit from NicFitNation - its the perfect length to fit on the collector tank.

If anyone's interested in buying a GG out, I got mine from
E-Cigz London, Discount Electronic Cigarette & cheap E-liquid suppliers, Atomizers, Cartomizers, Batteries, GGTS, Ecigs E-Cigs E Cigs E Cigz - shipping times were about the same as ordering from the US. Frequently there are ones for sale in the classifieds too, might be better to go that route. If we have another Lower Mainland vape meet, I'll bring the AVS and all the accessories along for people to try out.
