The delivery was quick and painless, so was the setup.
Assembly was straight forward and components are excellent. It probably took all of 20 minutes to set up. I limited my rating to 4-star only because I haven't yet had the chance to use it.
This does fit XTool D1 Pro
I tested the camera before assembly of the arm and found it didn't work. I took it to my work bench and gave it a once over but nothing stood out. Having experienced many electronic components from China I know there sometimes are problems with assembly. I took a dental tool and pushed all the wires into the JST connectors and resolved the problem.. I went one step further and hot glued the connectors together and the wires. Less chance of the small components from vibrating apart.
As for the arm structure, it goes together rather straight forward and it built very well. I would say it is almost over engineered for the purpose of holding a small camera. Overall, it should perform very well and last a long time.
Easy to assemble the stand and quick setup using Lightburn. You do have to get use to viewing the sideways image but after using it a few times, it become natural.
