The G Pen by Grenco Science

Meh it seems we've been gypped my friend. Or at least I have, since the inside of mine looks like this. http://imgur.com/lPOGO

I keep taking dabs but I'm not getting very high, and I thiiiink I can taste plastic.. or this wax just tastes like shit.

lol wtf ive never seen any concentrate look like that, whatever clinic your going to is shady i suspect, I hope you didnt pay too much for that "wax". Most wax ive seen looks like earwax of some sort, sometimes darker or lighter but you get the picture I honestly dont know what they sold you. Where you located? I know a bunch of good dispensaries in the santa ana/orange county area that have alot of lab tested concentrates , PM me if your interested .

Oh damn, I think that green is plant matter from being poorly filtered. Mine isn't gooey either, it's like an amber gummy tar. Doesn't taste exceptionally well, but does have a pleasant piney hash taste. Camera is broken so I had to use my laptop: http://imgur.com/cQPR0

I'm actually in los angeles, where there are many clinics that sell good concentrates. But last night this collective was the only one open, so I had to pick up from here or not at all. (Mary Jane's Collective btw, don't ever buy their concentrates).

In the end I couldn't tell whether I was inhaling shitty wax or just plastic.. I don't really want to smoke the rest of it but honestly I don't feel like just throwing away $30..

I got my MicroG and its the old Cloud pen style atomizer. Just bought a couple extra since i saw the new design. Im a little skeptical about the new MicroG coil, it looks like theres no more mini wick and just the coil now, but the screen just kills it for me. I remember when i tried to add a screen to my atmos raw it wouldnt vaporize/combust but i never tried oi in itl so I dunno.

On a side note you can buy a 3 pack of cloud atomizers from cloudvapez.com. I was hesitant cause their site is kinda sketchy, qnd i had both a positive and negative experience.

I recieved my package a couple days later opeend it up and had a smaller box in it with cloud written on it,open that up and its a charger. Look at the invoice and its addressed to someone completely different on the opposite coast. Call their number goes to voicemail just before beep someone pickes up and i explain the issue. He asked for my state and nothing else and then said that i could mail them back the charger and when they get it they would mail out my correct order and a couple extra atomizers. Hung up and filed a dispute on paypal requesting a refund and i sent them an email saying i would mail back the charger but i would just want a refund instead. IDA from cloudvapez emailed me back immediatly and told me I could keep the charger, the would mail me my corrct order and an extra atomizer and ship it first class/or priority(whichever was faster cant remember lol). I also got an 2nd email a couple minutes later asking about the name of the person I spoke to(the way it was worde sounded like she was pissed)

bottom line: i rceived my corrct order a couple more days later. ( the 1st one i tried came DOA but the rest are legit and i fot 4 instead of the 3 i paid for) so basically I got my correct order and a free charger lol the reshipment return address was addressed to CloudVapez but besides that i cant complain

Let me know if you think the old or new style atomizer is better, I'm probly gonna get a micro g and im guessing its gonna come with the old style, they sell replacements which I'm hoping are the new style with the screen. would like to know which one you think works better.

If it's actually purged well, you could always make some cannabutter or cannaoil. If you decarb it, you can add it to a small amount of strong alcohol (pref Bacardi 151 or stronger) and get a nice tincture. Hopefully it's just the taste that suffered and not quality, although they're both related...

Ahh okay. I'll probably end up just smoking it haha
Also, am I able to clean my cartridge? It's pretty damn gunky and I feel like that isn't helping.. I have the original G-tank.

I wouldnt advise it, most of the time trying to clean those types of tanks youll end up breaking it.

Annd yeeeebuddy, i have the old Micro atomizers and now some spaer cloud atomizers, which are the same thing, with the mini wic runing through middle and no screen. I know I pad has the new one cause he posted a picture of it on the other page, but he hasnt posted here since. I zoomed in on the pic from their site and it looks like just a coil and no wick under the screen, but it also does not look like the screen is easily removeable but i dont know for sure. Im very hesitant to buy it before i get some reviews, i feel like the screen will clog easily and or might not be as effecient...

do the essential oil tanks come with the sleeve and mouthpiece?

The screen is not removable, planning on taking a micro g apart when one breaks to see what's underneath. Appears to be no wick, just a coil like you said. I like the screen, it seems to capture and hold the oil in place and let gravity do all the work. The screen also keeps dust and things out of the heating element I suppose The taste seems better than the other cloud style so far. I sometimes get some gunk around the inner portion around the coil with the cloud type, maybe these micro g's with the screen will keep it cleaner inside?

Yeah, comes with sleeve, mouthpiece, and extra glass cover. I don't recommend the essential oil tanks any more, mine just broke today after only 2 weeks of heavy use. The top coils weren't fully lighting, wiggled it around and got it working again, then eventually burnt out for good. I'm going to try to replace the coil, but I ordered a omicron tank in the meantime.

I've read that I won't need the thread adapter (G-Pen battery -> Omicron cartridge), but if anyone knows otherwise please let me know.

I had contacted Grenco Science with my receipt for the Essential Oil G-Tank and received a reply that they sent me a replacement. Pretty damn surprising how easy that was. Great customer service from my experience, and if this replacement tank lasts then my opinion will change.

alright, I just signed up to the forum after lurking for a bit.

I've had the gpen and gpen mini for a few months now and I got my hands on one of the new styled microg atomizers last week. I was confused with the screen to say the least but I it tried it with both shatter and melted wax spread on the screen.

the concentrate vaporized after really heating up the element (whatever it is) and pulling hard. after a few times doing this and getting a couple hits I wasn't very impressed.

I found that the hits aren't as big as the old style. and after heating the element a few times it has an off taste. some type of burning taste that's hard to put my finger on. not the same as a burnt wick but unpleasant still.

I got this as a replacement cartridge from the beginning and their customer service has always been top notch. I'm probably going to end up dissecting it to get a better look at whats going on inside. I'll post pics when I do.

Yeah the taste you described kinda reminds me of the gentlemans brand cartridges. I just had thenpleasure of using one and while it does not have a screen, the coil looks like what would be under the micro screen(dunno just basing off pictures). The old style can be bought in 3 packs from cloudvapez.com if you have any problems email them and theyll take care of you, see post above for my experience

Check out this video on the gpen with all 3 tanks....oh and it's a must that you prime your wicks with vg( vegetable glycerene ) ...just put a drop of it on each side of wick and one in center..... This will make you wick not dry out and taste funny .

Update on the micro g pen tank w/ screen:


So far this is the longest lasting tank I've used ( 3 weeks straight) and it performs pretty mush the same as the old micro g tanks (pretty good). My 1st micro g tank only worked for 2 weeks and the 2nd only worked for less than 24 hours till it burned out (no screen on either).

No issues with the screen, or difference in taste from the coil?

Just tried one of these the other day, pretty impressed. I was heating too much and just got a hashy taste from my wax at first, nice rips, and good buzz. But then I started playing with how long I kept the button pressed in, and with a couple quick, 1-second pulses(1-2 wait 1-2), I was able to get almost as good a flavor as I do on my ti nail. I could really taste my skunk#1 wax fully. Definitely has my interest peaked and hoping to acquire one from Grenco Science, as soon as I hear back from them.

Just picked up a microG pen from my local head shop(big mistake trying to spend some $$ locally). Only to find out that it was missing some of the accessories and had the old style, wick cartridges, not the new ones with a srcreen covering over the wick. Definitely disappointed and quickly remebered why i like online shopping so much more. Of course, nobody at head shop knows about the missing accessories, and definitely not return the item or work with me...f#$% me, right? So I figured I would try contacting Grenco Science directly with my issues.
I spoke to a young lady,(who's name does not rhyme with Karen) who listened to my story and decided she wanted me to have the best experience with my microG. She asked me to just submit my receipt from my local jerk head shop and she would see what she could do for me. After receiving an email from her, I forwarded on my receipt and a small request. The CSR,whose name does not rhyme with Karen, replied back promising to send out my missing accessories and met my small request. Just having that horribly sick feeling of, did I just get screwed again at a LHS, alleviated by Grenco and a wonderful CSR, made my day!!
Just felt I should make note here and hopefully maybe make her feel a little good if she happens by and reads. Not trolling or schilling, just pointing out what I felt was somebody going above and beyond the call of duty.
Really simple device, imo. Charge, remove mouthpiece/ bowl cover, load a little wax(without touching wick with your pick/dabber), and rip. Very nice results for such a little device. I was looking for something cheaper to help me not go broke doing dabs all day. With the microG, I can just kinda "sip" away and keep a nice medicated state, without going thru a ton of wax($$). Kinda reminds me of how I used the MFLB. Good performance on the go to keep medicated thru the day without going overboard. More to come as obviously it is a new "toy". Let's see how it works over a few months time. I am excited to see how it does.FWIW, my daily home vape is the VXH Cloud and daily mobile was my Arizer Solo(which I still think is one of greatest portables out there, and will get a break while I play with microG). I dab with DG Fritted and Ti nail/Globe.

Grenco Science, thank you for picking up where the joke of a local head shop left off!!

Ya but you got screwed by Grenco Science too because this device is not made for hash, nor is it even made by "Grenco Science". What you bought is simply a Ego-W ecig cart that can be had for $8 bucks and plugged into any battery. Using this for hash will melt plastic and waste your oil.

If i were you i would try to sell the thing on craigslist, or try to say its broken and you want a refund. Because it will be broken soon. Also if you insist on it, buy your carts from planetvape so you dont pay $50 for a guy in china to put a G on your tank.

You realize hash is not wax right? Thanks for your thoughts though.

Hahahah i love this because i use it to describe a transposition(logic thing).

All wax is hash.

BUT that does not mean that all hash is wax!

I was talking about BHO or whatever you wanna call it, the point is the G Pen is simply a generic battery with a generic cartridge. YOU CAN GET THE SAME SETUP FOR 30 BUCKS. thats the point im just informing you i don't have any stake in the matter and you can use this info however you like

Links to setup for less than 20$

Retard neither of those are for the mico gpen....learn to read and pronounce your vowels sir, lol. You gonna quote someone about the micro g pen, then u post a link to the original full size ones, troll on sir , troll on

Vapezilla, when you see this post...

The links are the same pieces that make up the G-Pen. The only difference is that the G-Pen has branding and hype behind it. Most of these "pen" vapes are the same deal, a different combination of battery and tank/stripped (if you're that lucky) atomizer. The two items in the link will give you the same performance at a much more affordable price. Omicron/Persei/Revolution/Cera EO are the only ones I can think of off the top of my head that are pen-style vaporizers designed to be compatible with oils.

For what it's worth, they'd probably do pretty well as e-cigs. But the consistency of propylene/vegetable glycol is much different than BHO.
