I have had one for a year now. It's a daily-user - and in fact I'm sucking down a bag right now.
I'm not a "review" type of guy but me and my buddy both have had one for over a year and couldn't be happier.
Read the following because it's got a lot of good info about it and will save you all of the time I spent tinkering with it.
Goods:
Great price - I got mine for $130 from Vapornation.com by naming my price.
Lasts a long time - I use it for about 3-5 sessions a day and it's over a year old.
Remote control - it sounds dumb, but you have no idea how convenient it is until you can't find it
Really really gets you high.
Still has a lot of the same "smoke" effects (blowing out visible smoke) without feeling it in your lungs the next day.
Lots of spare parts - also part of the bad.
Bads:
Bags it comes with are small
The elbow is a little awkward to change bags on after each filling and breaks easily
The whip is a little too firm and causes the bowl to tip - I don't enjoy it but my friend swears he loves it.
The screen inside the elbow get's gunked up after a few sessions.
Tons of parts everywhere are easily lost and hard to figure out what to do with sometimes.
If I could start all over again, here's what I would do/want to know:
1. Immediately order the all-glass elbow from their website. The glass-on-glass connection and all-glass elbow are 10x easier to deal with between bags.
2. Go to the grocery store and buy a few boxes of the giant turkey-sized cooking bags. Use these instead of the ones they send you. They last longer, cost next to nothing (~$2.29 for a set of 2) and allows you to relax with a bag for a bit while the other bag fills up.
3. Get a grinder - I never had one before and it's a game-changer in general but a must-have for a vaporizer.
4. Set the temp to 205 to start with - that should last 3 of those huge bags and give you a decently dark vapor. If it's getting a little weak, I'll bump it to 206 for the third bag. After that it's bonus territory where you can stir it up, get 2 more giant bags at 209, stir it again, then 1-2 more bags at 212 depending on how full you filled the bowl. I usually fill 2/3 of it but even at 1/3 the results are phenomenal and last longer than you'd expect.
5. Fan speed 2 and Fan speed 1 produce the same vapor. I swore that I got darker vapor on setting 1 for the first 6 months and never even tried setting 2. My friend and I did a side-by-side comparison and taste-test and confirmed speed 2 and 1 produce the same vapor but speed 2 is just way faster. Your call.
6. A full session lasts around 25-45 min depending on how many bags you use, etc. so it's not the best device if you're in a time-crunch but it is the best device for a movie or big hang-out session.
7. Keep the air flowing = this means 2 bags at a time. The weed can only be vaped for so long. Stopping between bags seems to decrease how long the session will last. I'm getting 6 gigantic bags off of the same amount of weed I used to get MAYBE 6 factory bags off of when I first got it. The trick is to follow my pattern above in number 4. If you stop the airflow between bags it's like lighting a bowl and then letting it burn itself out while you're coughing your lungs out. I smoke at the fan-speed 2 pace and if I'm getting too high and slowing down I drop it to speed 1 to catch up. It works like a charm.
8. How water cleans most of it, glass cleaner works way better - especially on the elbow screens.
9. BUY AS MANY OF THE ROUND-BUBBLE ELBOW SCREENS AS YOU CAN. You will lose them easily. They will get gunked up easily. They're annoying to clean. I went and about a pack of 25 on ebay and didn't have to clean any for a year. Best purchase ever.
10. Don't travel with it. As someone that likes to watch people get really fucked up on the vaporizer (and yes, it WRECKS people) I am always wanting to throw my setup in a backback and bring it to parties and stuff. I almost always forget at least 1 essential piece and the opportunity is wasted. There's nothing like telling everyone at a party how cool your vape is and that they should try it only to realize you forgot the cord at home. It happened to me THREE times, including twice in one night! I've had some pieces broken and lost and everything generally mishandled when I take it places so just keep this at home with you.
I wish someone had told me all of these things when I bought it! It's a great piece, get's you high, get's your friends high who say "oh, weed doesn't get me high" because there's no faking smoking it with the bags, it get's your friends high who say "vaping doesn't get you high" and it get's me high every damn day!
If you have IG, check out @vapecanaveral and I think there's a video or two of the bag filling up and stuff.
Enjoy!
