I think they make an excellent garage ornament , as that is pretty much all they are right now.

Motors them selves appear quite well constructed. Seals on every joint etc. Bearings all feel nice. Keyed shaft is well machined. Drives appear well constructed too.

My only real gripe, is the 25 pin D connector that is on CN3.
It will have 3 or 4 different cable going to it eventually (including a shielded catb7 I think, for the encoder feedback).

Let you know more when my 24V PSU arrives.
