So last weekend I went to The Green Door in SF and bought this thing (and an 8th girl scout cookies!). There's been a good amount of talk about this thing so I figured I'd post and answer any questions you guys have. I know there are a few of these out now (Omnicron, iVapor RX, AtmosRX and I'm sure others). I personally got the iVapor RX, why? Because it wast the only one they had lol. I don't have any info on the other vape pens / w/e they're called so please don't ask. So here is the basics on this thing... It's about 4 inches tall and about a half an inch wide / deep. Each cartridge contains 60-80 (more like 40-60 hits) out of each one. Right now the flavors I have seen are Girl Scout Cookies, Cherry Pie, Sour Diesel and OG Kush. I have only tried GSC and honestly, it tastes like hash oil lol (I can't see different flavors changing too much, to me most oils taste the same, the highs obviously will be different). The high, it's pretty great I must say. I used to rip out of the bong multiple times a day and this thing does the job in a much easier way. You simply hold down the button and inhale until it blinks, then hold in the vapor as long as you can an exhale. By 3-4 full hits, you'll be pretty medicated. 1-2 and you'll have a good buzz. It charges via USB (no batteries!) and the charge lasts pretty long. So far i've only charged it in the car when I wasn't using it on a fair drive and it hasn't died once. I just got put up my bong on craigslist to sell, all thanks to this thing. I work all the time and have a pretty hectic life right now. Because of that it's hard to smoke when I want, even with a card it isn't right to go into meeting smelling dank as fuck lol. This thing gets rid of all the "negatives" of weed and gives you all the greats. I can smoke anywhere I want and in a healthier way. Now I'm not saying this is a bong killer lol. When I move out I'll have my bong sitting on the table when I get home....but it'll only be at home. My daily driver has now turned to this pen. It's healthier, gets you baked and you don't have to deal with the shittyness of changing batteries every hit, etc. For someone on the go that has to hide their weed smoking, this is simply the way to go.
