I don't think I need so talk about the performance, this has been done enough. Just be aware that the build quality is not consistend. The 510 on my device is crooked and nothing that I own sits flush. Tested more than a dozen RDA's and RTA's and everything has a gap. With some RDA's up to 1mm, that just sucks. Especially since I already had one these almost everything I owned sits flush on this one. I ordered a second one but obviouly caught a really bad batch.

Waste of money. The only thing that's good about this RDA is the copper top cap, it goes well with my copper mech mods. Everything else sucks. Flavour isn't good. From the outside it looks like the the top would be curved, but it's flat inside. The afc is the biggest problem. If you use this with 2 coils and you want to close it down below 60% the single coil slot starts opening up. That's something I expect from a 5$ clone, but not from a original. That makes for an uneven draw, because you get more air from one side than the other, which makes for a rather annoying experience. The o-rings suck. After removing the top cap a dozen times they are already falling apart. I can't recommend this device, there are a bunch of better options out there, stay clear of this one.

A good RDA, decent flavour, rather easy to build, good Airflow and a good juice capacity. Downsides are that the device can get very hot, depending on the build you put in. Don't expect having a good time vaping this @ 130w or more. Also Kennedy and Goon DT's don't fit. I'm running this device with SKU 5819101, fit's perfectly and helps if the RDA gets too hot.

The DT get's way to hot with this RDA. I've put in 2 SS Clapton @ 0,2 Ohm. After 2 drags the DT gets way to hot to use the RDA. I have to let it sit and cool for a minute or two before I can use it again, otherwise I burn my lips.

Got mine today, first problem, the RDA doesn't fit. Forced it in with pliers, now it works, but that's not the way it's supposed to be. Second problem is the paint, simply put, IT SUCKS! Scratches very easy, my mod already has scratches all over. Third, no venting, this is an explosion waiting to happen. If you want to use this mod and be on the save side you have to drill holes in the tube. Now to the good things, this mod looks awesome, it's nice and heavy and it hits hard. The last point was to be expected, it's a massive copper hybrid mod. Now it goes on the shelf until I find the time to drill some holes in the tube, but ey, at least it looks good. :D
