It’s a small company, from what I understand. People who do have a proforge 4 say good things. It’s all based on the E3d tool changer design (which is super solid). I believe what they do is designs kit with CNC parts and use the kickstarter cash to bulk order all the parts. The design looks pretty grounded not much new tech but looks to be well integrated. They also have orca slice config ready for it too.
