Don't lose the little screws that hold the sled together when you rinse out the silicone bottle. There are extras, but the additional tanks supplied don't come with more so I try not to lose the originals and have to jump straight to the only backups provided that I may need down the road.
Other than just have fun with it. It's simple and it works. The refill system is dead simple and the menu the same. You can update the firmware to add TC if you want it, but it requires like three hands to get the up:down buttons pressed while holding the mod and somehow clicking your mouse to do the upgrade. Once you're done with that little contortion it's a snap (why do they never consider user friendliness on firmware updates, I know they're not software companies but really, this stuff isn't hard).
However, when you do add TC you'll just go back to wattage becsusevi found it lacking in that area. That's what the upcoming Drone is for.
After all that seeming negativity I'll say it's one of my all time favorite mods. There is supposedly a dual battery version poised for release which I may also get. It's definitely a joy to use with 10 ml on board and a 21700 40T to power it. It's absolutely in my daily rotation, generally with a circus candy juice I really like as my evening to night choice. I've used everything from a Recurve (finally figured out a good build for performance at least for me), DR RDA, a Haku and a KRMA and even an Aura and love the whole setup.
