Hey Xanalog!
I, too purchased the Ultimate Kit. I quit smoking analogs after 30 years 1 to 1.5/ppd and 07/07 will be 30 days for me, so I'm grateful to the kit for that. After getting the kit - I really like the 808 design. It's easy. I also prefer the XLs. I initially got 2 with my Ult Kit and so far, for the XLs, they last all day and I've topped one off every morning and get a full charge in about 30-40 minutes. The only other stuff I use out of my Ult Kit is the USB Charger and the pass through. The shorties were not for me - died after a few hours.
I quickly bypassed the prefills and went right into filling my own cartos with juice - because of the bazillions of flavors. I personally do not like not being able to control the consistency of a prefilled carto. I'd be remiss if I didn't refer you to Vermillion River Ejuice! Simply wonderful juices. I smoked Marlboro Lights and I started out with 18-20mg of nicotine and it seems to be working for me!
I've since purchased other XLs from other suppliers at a lower price because I really like the simplicity of an 808, and I wanted different colors. I really like all of my XLs but my new ones from other vendors have died out during vaping and last about 6-8 hours. (V4L and LiteCigUSA). I'm not complaining by any stretch - I love them all - I just can't personally figure out why my original XLs are lasting twice as long on a charge. Upon physical comparison, the V2 XLs are slightly heavier and fatter.
I learned that the KR in the 808D-1 stands for Kangar or the manufacturer. Sometimes you just see 808D-1, which just means not manufactured by Kangar, but same threading.
I have a nice little 808 collection now..lol!! My next move, after one that I have completely crashes and burns is to continue my experiment with Bloog, the KR808D-1 from Nhaler (its the only KR808D-1 model I've found so far so trying in terms of Kangar vs 808s.) Myvaporstore also has some really good prices.
Personally the 808 just works for me and I do realize that down the road I could change my mind - but I doubt it. I like they way the look and work. My next step up from here is keeping an eye out on the G5 clearomizers. These are clear cartos w/o the batting - which I really like the idea of no batting and being able to SEE when my juice is about to run out!! When they perfect this...I think I'll be in the perfect spot!
Most of all - just DO IT!! Make the switch! I cannot believe how easy it's been to quit analogs and most of all, my wish for you is to just jump in. My biggest regret is not doing this sooner. Regardless of which way you start - this will be your new obsession and where you end up might be way different but the important thing is...go for it!!! Look how far I came in 30 days!
Welcome!
