So after 2 days of non stop research my head is throbbing and I cant seem to make up my mind! The 2 biggest factors that make me lean toward the KR808D-1 is size and affordability. However I've read so many good things about the Joye and the color/led options are very cool. Im looking for something that mimics a real cig quite well. Right now I am using a disposable cigalectric I purchased from 7-11. A couple days using it and Im sold! However the cartridges are quite expensive for that brand and the starter kit is $60 with only one battery. So I've been hunting for a similar alternative. Any advice would be great! Thank you
