The plate itself is really nice. Has a good finish that is robust. The size is accurate. The jack hole is large enough to accommodate the thicker Switchcraft thread jacks. For what it is, it is very hard to fault the plate itself.
Downsides: the screws supplied with it are not great, the heads started rounding out when it was being installed even into drilled holes. I would say also that it is only good where the surface it is being fitted to is perfectly flat. If you were hoping that it could be made slightly curved to match a contour on the body, bending it would be very difficult.
