I've tried a lot of rba's from the Phoenix and it's knock offs to random genesis style atty's and most recently the I go-L. This cyclone may just end up being my favorite. It's sleek and stylish and a cinch to rebuild. The craftsmanship is flawless. I'm starting to prefer the o-rings on the tops rather than the threaded ones. Makes lining up the air hole a no brainer. The 1mm air hole may be a tight draw for some but suits me perfectly. Been using mine for a few days now and have experienced no leaking and the top cap hasn't shifted position inadvertently. The Allen headed screws for the coils are extremely tiny. I could see losing these. The cyclone does come with its own Allen wrench, silica wick and wire. I have the top feed version for dripping but they also have a bottom fed version. I learned just today that the center pin can be adjusted just by tapping it from the bottom with a hammer and screwdriver. Thanks to Jay from vicious ant. Overall I'd highly recommend this rba. Purchased mine from Indy vapors but it's available at other vendors as well.
