I got this for my Epiphone Les Paul a few years back and was amazed at just how good it was.
Build quality is excellent.
It was easy to install (the saddles were pre-slotted), and you can just use your existing bushings if you want, but I used the ones that came with it.
Setting the intonation is a breeze as the travel on each of the saddles is smooth and does not suddenly jump like the stock Epiphone, or even Gibson, bridges. There is also more travel, so whatever your action setting, you can dial in the intonation with no problems. Once you have got everything set as it should be, you use the little allen key screws to lock the bridge in place.
What I really liked about this bridge though, was when I checked the intonation again over a year after installing it - still spot on, despite numerous string changes (my sweat eats strings), fret polishing, oiling the fretboard etc - it hadn't budged at all!
Loved it so much that I when I needed to replace the bridge on my Gibson SG, I headed straight for the imperial version of this bridge.
