Just got my cylo today and so far, it's a solid performer. The atty included clocked in at 2.3 ohm. Filling is fairly easy, but you'll need a needle nose bottle to do it.
VFT is very good, comparable to an Evod, with a nod toward the Cylo for flavor. Compared against dripping (Vapage 2.5 ohm), the Vapage atty is a (small) step above the Cylo in VFT IMO.
Only had this for a day so not sure if there's going to be any leakage issues yet. But, looking at the quality of the build, everything sits together nice and tight.
