Just got one not long ago today and I have to say that this is a really nice tank. I love how it is short but stubby, so I can hold 4 ml of juice but is not towering. It fits perfectly on a Sigelei 213 and looks great on the smaller mod. I haven't tried the RTA deck yet, but I have tried the included 0.3 ohm pre-built chip coil. The positive pin on the 510 sticks out quite a bit, therefore you would definitely be able to use this on a hybrid mech mod. The way the pre-built coil is made, it is extremely similar to a RDA so you get a dripper performance from a prebuilt coil. It comes with dual twisted coils and the flavor and vapor production is on par with a dripper and you prime it just like one. A few drops onto the cotton and the coil to ensure that it is properly saturated, screw into the tank, fill the tank and you can start vaping immediately. This coil does go through juice just like a dripper though, so even though it holds 4 ml of juice, that juice will go quickly. The RTA is very similar to a Griffin.
The biggest plus is I've gone through two tankfuls of juice and have not had any juice leak at all. And lately I've been having a lot of problems with leaks in different tanks. There has been some condensation build up in the base after two tanks of juice which if I blow forcefully through one of the base air holes, a single drop will come out the other side.
The tank came with a clear glass, with a spare color change glass (dark glass that turns white translucent when it heats up), the chip coil, the RTA base, spare o-rings and Allen key, and a spare drip tip. I also got an angled chuff cap (installed in picture). The opening in the standard drip tip and the chuff cap is the size of a 510 drip tip, so you can simply plug your 510 drip tip right into the existing one. The standard drip tip (and the chuff cap) is pretty short, so if you are using it, your lips will be touching the top of the screw on cover, which will start to heat up if you start chain vaping. I like this tank so much that I'm ordering another two plus some more of the 0.3 ohm coils.
