The jury is still out on that. It's my first headless instrument, so I have to get used to tuning at the bridge. My hand still reaches for the headstock intuitively...I have no other headless systems to compare it to.
These are ABM bell brass tuners and the construction seems good, but they are a little hard to turn under string tension. I don't know if that's normal for headless tuners. When I was working on the nut slots and setup I had to loosen and tighten the strings a number of times, and my fingers still hurt from turning the knobs. I've seen some people put bearings or washers between the bridge and the knobs, I wonder if that would help. However, for normal tuning purposes I think it's fine as it is.
What I liked about the ABM bridges is that they come with unslotted saddles, so I could fine-tune the string spacing by filing the slots myself. By fine-tuning I mean very small offsets, nothing major. With the unslotted saddles the strings had too much sideways play in my opinion.
