Got my second Go-go kit yesterday - this one from cigeasy. As others have noted, the cigeasy ones are black and silver, as opposed to nhaler's black and gold. These also have the blue cigeasy logo on the battery which really is no biggee for me - I just call it my "designer" Go-go, and it makes it easy to differentiate between the two models.
The cigeasy kit came with the black wrapped carts instead of the newer carts, and I suspect this is because I chose the pre-filled 24mg Marlboro option. It would've been nice to have gotten the newer carts, but I'm kind of a cheapskate and couldn't turn down the extra juice. I also wanted to compare the Marlboro juice with that I received from nhaler. Not a huge difference, but a difference none the less.
Cigeasy also included a sheet of instructions - not all-encompassing, but useful tips on some of the charger issues that have been discussed here. And, of course, anything is an improvement over the standard Go-go user guide which has to be the most laughably inept instruction manual ever created by man.
More juices and LR carts are on the way. Woo-hoo!
