I can say without hesitation that the quality of the Les Trem II was excellent. However, I did not like how it felt when playing the guitar. The trem unit sits too close the bridge and doesn't allow enough room to comfortably situate your hand between it and the bridge. I don't have big hands, but I like to have enough room to strum the strings without restrictions. For me, the trem unit restricted my hand movement. So I uninstalled it, and sold it.
I can say the installation was quick, and the it actually looks nice on the guitar. If it was to be re-designed, so the activation arm is moved back about an inch, I would consider buying another one.
