I completely forgot about those. When they first came out I'd planned on getting one set to try sometime,,,,,,,just never did.
Now being much more settled on my gauges and tunings the need just isn't there for me, and bumping a saddle back or forward only takes a couple minutes total anyways.
The one thing these really have going for them is their ease of preciseness.
Not every newer tech/player can set them right without over/under-shooting the adjustments a few times back and forth lol,,,,,,,,,it can be very frustrating until you get the touch.
These fancy gadgets don't take away the fact that when you set intonation; the relief, action, bridge-angle, and note-pitch(tension) all have to be dialed-in exactly how you are going to run them,,,, otherwise the saddle adjustments will be a waste of time.
