Finally! a Red X I was beginning to wonder if there were any BF'ers left out there?
The K-F V5 is a great RTA! It has just enough Air Flow to do a restricted LH, it's a solid design & consistently works well

My 5.2's (ulton) have a very short 510 pin & are very limited to the mods they will work on

Even thou they are great performers with more air flow than a V5, the constant resistance issue's from the short 510 have caused me to abandon mine

I see now there is a new 5.2 SE, only difference looks like a wider DT, & a different tank section. I'l pass on this offering & stick to the V5
