I ONLY drip. I don't use any tanks. I either top feed on RDAs or I use my Reo. The only atomizers I've used for a year now have been the A7 bottom feeding atomizers. The air comes from the atomizer's 510 connection's holes, and a hole in the center post. The air travels through the bottom body of the atomizer and is sucked to right below your coil, through a raised tube with a hole in it in the center of the rebuilding deck. This means that this little air tube supplies a ton of air right UNDER your coil, which is ideal in my opinion. This little air tube doubles as a juice tube when your using the A7 on bottom fed mods, such as the REO and the BoggerBox. The juice travels from a bottle inside of the mod. You press the bottle, and juice travels through a tube connected to the special bottom feeding 510 connection. The juice is sucked up through the air channel in the A7 and it wets your wick precisely & efficiently.
For this reason, I love A7 atomizers. However, they CAN be a bit difficult to tame. The posts inside of the A7 are actually facetted to the atomizer by threads. This means that the posts can be unscrewed, allowing for reconfiguration of the wire holes. This is more of a curse than a blessing. If the posts were stationary, facing each other, it'd be fine for small coils using a thinner kanthal. But since the posts can be screwed to different increments, the A7 allows for longer coils, with 26-28g kanthal as well. This would be fine, if the posts didn't move when your trying to tighten or loosen the kanthal screws in each post... You can overtighten or loosen the posts!
Beyond that, the A7 has an adjustable center pin. This is also a blessing and a curse. This basically means that the center pin can adjust into the A7s 510 connection, or a good bit OUT of it's 510 connection. This can allow for flush-mounting on mods that don't normally allow for flush mounting.. Mods with center pins that were made too long for use with button top batteries, such as the natural. The PROBLEM with this, is that if your using the A7 with the center post unscrewed all the way, it can (& eventually will) short your mod button, spring, or the battery out. So you've got to be careful with that, especially on mechanical mods.
Other than these quirks & limitations, the A7 delivers, by far, the best vapor out of any RDA I've tried. There is no worrying about a hole in the top cap aligning with the coil. The juice well is deep enough to allow for at least 2 separate entire vape sessions. (with cotton) Since the air hole is in a raised tube, you don't have to worry about over juicing. Your coil can easily be made above the posts. Since it is a screw top atomizer, you never have to worry about the top cap & drip tip staying in your mouth, as your mod drops to the ground. Since the juice well is so deep, you can take 20 hits before redripping. NO airhole aligning needed. NO easily broken ceramic parts. Replacement screws are found online easily. Entirely made of stainless steel, NO brass parts as far as I know.
All for under $20. The A7 is by far my favorite atomizer. Unfortunately, they aren't as popular as they should be, and the company doesn't typically put their company name behind their products. I believe the A7 is made by "Sailing" though, I could be wrong. Sailing has consistently made good quality APV components, but they just don't get the spotlight very often. Its like the makers of the Vamo. Who makes the Vamo? Smoktech? Kanger? Sailing? Rainbow? Teardrop? Redbull? I have no idea. I'm guessing the Vamo is made by different companies, similar to how the Lavatube V.1 and later the Lambo were made by many different companies.
All I know is, the A7 is a fantastic atomizer that deserves more respect. I am very unsatisfied with the current RDAs & clones on the market. They either have screw-on caps with airholes too small or unaligned with where the optimum spot for a coil is... Or, they are fitted with poor fitting O ring caps that slip off with the faintest pull on the drip tip, getting your hand dosed in nicotine and potentially dropping your new $100 mod to the floor. The A7 got it right the first time, and I cannot believe there aren't more bottom air-fed atomizers on the market. I cannot believe no one has cloned the A7. Especially considering there are so many Reo lovers out there.
On top of this... The A7 is becoming increasingly difficult to find. Some companies are price gouging at $17-20 a piece. Some are selling these at $12-16 dollars a piece. I think it should be a $10 atomizer, WIDELY available. As available as the Igo-L, honestly. I don't think it needs much improvement, and I can't believe this bottom-air bottom-feedable RDA design hasn't skyrocketed in popularity. Unfortunately, I'm sure this post will sell 50 units on the website that shoots to the top of the search engines for A7 atomizer. Thats how ECF works. I already have two and I can't afford a 3rd, so have at it. I just needed to share that the A7 is by far my favorite RDA.
