I have nothing against the kuro coiler, but I prefer the Coilmaster V3. The longer, removable rods make positioning the coils in your rebuildable a LOT easier. And if you're buying the genuine article, for $25 for the Coilmaster gets you the tools to wrap 6 different sized coils. With the Kuro coiler, it's $20 for one size only.
I own five different coil making tools (Qvapes coiler, Aerisphere Micropuck, Kuro coiler CW25 & CW30, Coilmaster V1, and Coilmaster V3), and the Coilmaster V3 is my current favorite of the bunch, even though I've had it less than a week.
