To add my observations about their reliability: WN&G made a two-note action model for my string testing device. This action model has been packed and shipped, bumped and abused and generally treated in ways no proper piano action should have to endure. It keeps right on working flawlessly; its regulation is stable and the composite shanks and plastic bushings have put up with side knocks that would have destroyed conventional wood/felt parts.
