The Cig2o is a retail product that has been showing up here in So. Florida in some of the dedicated tobacco shops around town. After some research I found it to be a rebranded KR808D-1. Which, after some research, I discovered is not a bad thing. I picked up mine for 45.00 and it included a couple of cartomizers, the battery, A USB/wall charger, and instruction book. Since I was spending over $33.00 every 10 days for my cheap 305's, I decided to take the plunge, and purchased the Cig2o. Boy am I happy with my purchase. Now I understand that I could have gotten a cheaper KR808D-1 online, but there is definitely something to be said about having the ability to walk into a store and pick up a unit and if you have a problem with it, returning it at the store. Especially if you are a skeptic, as I was. The Starter kits come with one of two types of cartomizer, "tobacco" and "menthol". I purchased the "tobacco" starter kit and am very pleased with it. It has pretty good flavor (at least a lot better than the cheap ... cig's I was previously smoking), a decent throat hit and a decent amount of vapor. What is odd, however, is that tobacco refill carto's are not available. I contacted Cig2o and they said that they underestimated how much people would like the generic "tobacco" flavor. Their website has a handful of flavors available, and their website includes free shipping on all their products which is nice. I have been using my e-cig for about a week, and I can't tell you how I impressed with it. I smoked the first day of purchasing it to "close out" my last pack and haven't had the need for an analog since. My cig2o even passed that most stringent of tests: The post-cloital cig. My girlfriend has a blu and is not at all happy with it, but last night took a couple drags from my cig2o and her eyes got wide and she said that it was nothing like her blu. She's back on analogs and I haven't looked back. I may try and get her to return the blu and get the cig2o. So that's about it. The cig2o is a retail rebranded KR808D-1 with all the benefits and shortcomings that come with this model. It's a great starter 2 piece e-cig with great cartomizer support from third party vendors like vapor4life.com It's not the best or cheapest e-cig out there, but is high on the list, and it's wide support base make it a great way to start vaping. Hopefully companies like Cig2o will get better market penetration so I can start buy my supplies at the local Walgreens instead of online. Until then, I'll continue vaping my Cig2o and appreciate each day that I am smoke free.
