Mini Rambo Electronics Controller Kit V1.3 (with connectors and USB Cable)

The board I had in a kit printer went bad - twice. I had to wait a month for the first one to ship. It was literally on a slow boat FROM China. I didn't want to wait another month,so I went ahead and purchased this. It arrived promptly and the customer service was awesome helping me get it running. Not because there was anything wrong, just because I don't know much about 3d printing yet. Only knocked off one star because it doesn't fit the mounting on the printer I have and I had to rewire all my motors because the plugs weren't the same. Not the fault of this board, so really not fair to take off a star. I'll put it back on :)

They have no customer service. I reached to get support and possibly an exchange. I received no contact back. Would never buy from them again.

great little board works perfect, I'm using it in my original Prusa I3 MK2 3d printer that i built from the upgrade kit and am using the Prusa Research firmware with it, I have had no problems with heating or long 10 hour prints.

Works great for my Prusa Mk 2.5s.

I upgraded my Prusa i3 HICTOP and my quality jumped up 5-10x and it ran for 3 days with no issues. Loving it!

Flashing and installing was simple.
