tHIS IS MY FIRST REVIEW ON ANY PRODUCT FOR THE PUBLIC TO SEE! I hope I explained things in the best of manor and if there's anything I can improve on, do let me know 
First, I'll admit that I was a little hesitant on the price of this tank as it includes so much for such a little price. I was told about the tank on a local Facebook group for strictly vapers ranging from beginning vapors to people who make full blown mods. A lot of knowledge on that group, and this is my thank you for helping me find my new favorite tank.
The tank can be viewed here - AGR Carto Tank. So what do you get for the small price of just, $14? You get: A 510 to 510 adapter, long and short body polycarbonate tanks, stainless steel bottom and top cap.
This is what you'll get when you first unbox it. The tank is wrapped up about 5 times in bubble wrap and the extra tube and 510 to 510 adapter was in their own little plastic baggy.
We'll go ahead and start off first with the tubes. The short ones will work with your standard Boge (which I use) or any single coil carto that isn't an XL version. The tubes have threading on the top and bottom where your end caps will go on so they're not like your typical top caps that just squish into place. The end caps both have an o-ring on them so that you'll not have to rely on just the threading to keep your juice in unlike the Vivi Nova's (or so I haven't seen any with o-rings)
Now, the end cap were the connector part of the carto goes to the tank does NOT go all the way through. Steammonkey got pretty innovative as they decided to do away with the o-ring on the bottom that some people have troubles with on cutting them when inserting a new carto and then that seal is now broken until that o-ring is replaced. So you ask: "How does the tank not leak then?" Well, here's where the 510 to 510 adapter comes into place for two reason! 1. Since the carto stops at the end cap, the 510 to 510 adapter now locks that carto into place so you now longer have slipping tanks on a cold day when the rubber starts to shrink or they're just not good to begin with so you wont rip your tank off and then say bye-bye to your juice and hello mess! The adapter also allows you to have a good connection since the kilt is on the tank, not a skirt! It's integrated into the tank itself! The adapter is quality made and I have yet to have any problems screwing it on or any issues with loose or grindy feeling threads. And as Mr. Phil Busardo would say: "buttery smooth."
I must warn you now: IF you DO NOT have the adapter on the carto when you try and pull your drip tip off, you WILL pull the carto out of the seal and you'll be left with a lap-full of juice.

Filling this tank is very very very easy. You can do it two ways. You can use the fill hole on top by removing the little screw and using a syringe to do so OR you can simply unscrew the top end cap and fill it just like a Vivi Nova! Now I must warn you, if you choose to take off the top cap and not fill the tank with a syringe, you more than likely will flood the carto since you're forcing all that extra air into the carto since it has no where else to go, but you can blow the excess juice out easily. This has happened to me twice already and it hasn't a single time since I've filled it with a syringe.
Since there is a fill screw on top of the tank, unfortunately, your ming or pawn style drip tips will most likely not fit. I did have one ming style that did fit and it'll be in the finishing product photo.
And here is the final product!
Let's talk about the good points of the tank: 1. Very easy to fill with either taking the top cap off or through the fill hole. 2. Very inexpensive and almost if not all vapers can afford this carto tank. 3. Comes with a standard and XL size tank for people using dual coil carto's or XL carto's. 4. Looks absolutely spectacular.
Now, the bad: 1. If you fill it by unscrewing the top end cap, you will flood the carto. It's nearly inevitable. 2. The 510 to 510 adapter likes to either get stuck on the carto or the actual device. Sometimes it changes. 3. The tanks will more than likely not stand up to your cinnamon based juices or ones that could crack or glaze the tanks.
All in all I'm VERY pleased with the tank from steammonkey. This is something that I would recommend to anyone that wants a new tank at a cheap price!
