The build quality is very good for the money. I was able to easily set it up to my preferences : having it low with just enough gap to pull up 1/2 step before hitting the guitar's body. The saddles are easy to adjust and allow fine setting as well. Got the right intonation without really trying. The springs are strong and flexible. The trem bar is easy to lock in, holds well on its last position and doesn't demand to pull very hard to remove. Even with vintage tuning pegs, my guitar keeps remarkably well in tune. If you're converting a 6 holes to a 2 holes tremolo, you'd better invest in a drill press. It is easy to drill the two holes but it gets difficult to perfectly align the strings with the neck.
