GeekVape Ammit MTL
Although I have quite a few MTL atties in my collection, I'm no longer what I'd consider an MTL caper. Oh, I pick one up from time to time, and The Wife prefers that I use MTL when we go on a trip so as not to fog her (a non-vaper, never-smoker) out of the car, but it's not my ADV by any stretch. This might be because I am down below 3mg nic and don't own anything higher. This means that I end up reaching for my DL rig halfway through the day because I don't feel like I'm getting much from any MTL atty.
That's all to say you might take this particular review with a grain or two of salt...
The Ammit MTL is a 24mm RTA that measures about 40mm tall. It'll hold 4ml of liquid. In the box you'll find a spare glass (none of 'em bubbled), two 510 drip tips (one has a 2mm ID, and the second one is 3mm), a bag of spare o-rings and screws, a T-tool, and a couple coils. Note that the gold plated center pin on this tank really protrudes... if desired, this will work just fine on a hybrid mech. Why you'd wanna do that is beyond me, though...
I guess I should also point out that there's shorter version with a 2ml capacity for TPD compliance.
Filling is easy... unscrew the top cap, and squirt your liquid one of the two provided holes. Taking that top cap off takes a little longer than may others... a little over six full turns.
Under that top cap is the airflow adjustment ring. On one side of the ring, there's a single hole. The other side features a slot. The hole or the slot can be positioned over the five airflow holes beneath in a bunch of different ways. I rather like just using the largest single hole, or the three smallest. With all 5 holes open, this tank will allow a VERY restricted DL pull, but I feel like the flavor suffers there.
Building is just as easy. There's an offset two-post deck with decent sized philips screws accessed from the top. Between these posts is a block that delivers air to one side of the coil. There's another hole that delivers air to the bottom of the coil, and a raised block opposite the posts with yet another air hole. To either side is a wicking hole.

I'm using a 2.5mm 6 wrap 24AWG SS316L coil in there, and I find it unnecessary to fluff or comb the cotton. I think it might just be possible to tuck a 3mm build in there, but then a bit of combing would be advised.
Like many of the current crop of Top Air RTAs, this one is using a double-walled chimney section that delivers air all the way to the bottom of the deck, and then up to the coils and your mouth. That chimney is domed.
The flavor is good, and the vapor is what you'd expect from a MTL setup.
Cons? I'm feeling spoiled by all the pop-up, swing-open, quarter-turn fill methods and this tank does not deliver. Also, this tank feels as heavy as some of my much larger RTAs - that either says something good about the amount of material used in this one, or something bad about the materials used in the others. The post holes are not staggered so the coil will have to be twisted a little bit, but that's VERY nitpicky. Some might say that having three airflow ports on the deck of an MTL RTA makes the throat hit sloppy, or reduces the flavor. Finally, it doesn't seem to come with any cotton.
Pros? Everything else! I mean, it won't leak, reasonably priced, dedicated to MTL, offers decent capacity (outside or TPD), easy to use, comes with a spare glass and spare drip tip, comes with a couple coils... I even think it looks pretty good.
If I was a dedicated MTL vaper, I think I'd be OK with this. BUT, I'm not a dedicated MTL, so...
