I bought this bridge as a replacement for the stock one on an Edwards EX75 (Explorer clone from the 90s).
The build quality is great, and compared to the stock bridge, this one provides more space for the saddle to move, therefore better intonation adjustment, and the posts will slightly improve sustain. The saddles are nicely fit, they don't cause any unnecessary noise and they move nicely when adjusting intonation.
Be aware of the following:
-I personally needed to drill holes for the new posts since these are way thicker than the original ones.
-The saddles are barely notched, if you play with heavy string gauge, like 56 on the low E for example, you'll definitely want to make deeper notches.
Bottom line:
The Gotoh GE103B is a fantastic product, and it made a huge impact on my instrument's performance. 5/5
