Review on 🔩 Optical Linear Actuator with Double Ballscrew by Justin Guldin

I found this actuator to be of excellent quality, better than I expected. He came much earlier than expected. The only reason I gave it 4 stars instead of 5 is that the locking mechanism didn't work when it arrived. I found that the screw went to the bottom of the hole so he couldn't tighten it enough. So I had to cut 2mm off the end of the screw to shorten it and now it works great. Overall I think it was a great purchase.
