The package is simple. Just a cardboard box with the mod and manual. When I insert my 26650 60AMP battery it's kind of flush with the mod so I didn't think my bottom cap was going to fit but after trying to close it there was no issues with the bottom cap. I tried my 22mm Orchids, Atlantis' and my 30mm Stilare and 30mm Genitank Giant and they sit flush with the mod. It's a floating 510 PIN so all the attys I tried sits flush. When I put the battery in, only 3 bars was showing full. Not sure if they all do that or if mine is defective. I'm recharging my battery now to see if it's the same tomorrow morning. So far using this mod is a treat because it hits hard and works pretty well. The up button does seem a little difficult to push as it didn't respond right away. The down button doesn't seem to have any issues. I'll continue to play with it and see how it goes but like I said so far so good.......

This thing is phenomenal! My orchid, Atlantis, Tobh all looks awesome with this. They all hit great. The lip of the top cap makes all 22 mm attys flush. Something the 20watt version doesn't have. Overall I'm very pleased with this unit!

Just received this tank and am blown away by it. Has better airflow than Orchids especially in RDA mode. Posts are clean, fits on all my mods.

well, I received this unit today and built a 0.2 ohm dual coil build on a Mutation X V4. Works flawlessly. I noticed that when I inserted 1 battery it turned on. My Mutation X V4 sits flush as well as my Orchids. The battery cover is decent with the magnets, touch firing button works flawlessly. Overall happy with this mod except the size. So used to using smaller mods.

Easy to build coils with lower gauge wires. Great value and in stock!
