Dome Crushing Stealth Mode

I think we have seen this design before….ahh yes, just last week.  The Atmos W.  The differences are slight, but the result is the same.  WHaaaaBAM.   Massive vapors in a minimal package.  Its a bit messy, or it could be, but that is to be expected.  They could have cut the price nearly in half, as there are actually two difference units in the box…but the battery doesn’t last long so they wanted to make sure you had a backup ready to go.  Its a good vape, that is borderline great.  Check out the video and see why!


2015 UPDATE:  After nearly a year with the OG microG, and a few months with the new microG, I can say that this is still the best elips-style pen vape on the market.  Its common design, you can see it everywhere.  We’ve used at least 20 other vape pens of the same design, none can compete.  The either leak on the first use, or get clogged so badly you have to toss them.   The microG stands alone.  Straight to the dome, every time.  No atomizer lasts for ever, we usually get about 4 weeks of HEAVY use out of ours, maybe 25 hits a day.   

microG Pen Vaporizer Video Transcript:

Hey Everybody, Vapeologist here with a review of the microG pen vape for liquids and concentrates from Grenco Science.  which makes a few models  of pen vapes.

IN the box are actually two microG Pens and a retractable USB charger.  Only one end is USB, the other is the old school barrel style, so don’t lose this, its not as easy to replace as your normal micro USB chargers that everyone is moving to.  There are also five silicone mouthpeice covers, and a keychain/tool thing.

microG vapes come with a built in safety lock for the switch, so clicking it on five times will turn that off and allow you to use the pen.  Charge it up and its ready to load.

Its a simple setup, the G uses a metal wire wrapped around a wick to heat your concentrates until they atomize.  It likes the thickest liquids or concentrates you can find. After you load it up, cap it, and now you can start vaping.  Or atomizing…or

The thing is about the G..it frackin works!  It produces nice tasty hits that are completely cool!  The purer the concentrate you put in the better, sometimes there is particulate from the process still in the concentrate, and that can combust easily, but its usually so small that it should not be an issue.

Aways insist in quality concentrates!

Its best not to put too much into the unit, as it could spill out if you aren’t careful, so either use it all up, (which is obviously recommended)  or remove the MP, stand it up vertically, and allow it to cool.  The battery life is okay…it lasts for about 5-10 sessions before I get power issues.  For some that could mean an hour, for some that could mean ten days.  You will definitely want to keep you charger close.  

The warranty is a year, which is good for a pen vape.  The price isn’t bad but if they only sold one a time, they could know that down a bit, no?

It isn’t perfect, but this little pen worthy for people that like to wax there car, wax poetic, or just generally like to wax on or wax off.  .  I could go on and on about the various situations where this would shine, but we don’t have all day.  Keep it charged, keep it loaded, and keep yourself VERY happy.

VERDICT: I keep an clean microG on me for emergencies at all times.
