I know this is the wrong place to put this comment, but I can't post in any other place. So here goes. I have been using the Xhale O2 since 9-3-10. Joined this site right after that. Battery life sucked with the Xhale, so I started to search as many reviews as I could read. After searching this site, I decided to buy a 510 USB V2 pass Thru with a battery and some empty cartomizers from Digital Ciggs. The price was right to create a new 501 e-cigg from scratch. I ordered it Sunday night and it came in today. Everything that I ordered came in and DC also sent a sample of Honey Beez. A very nice lagniappe. I even got a note from the owner thanking me for my order. I WILL order my e-cigg supplies from DC. Thanks DC for the great service.
