A great price on a DRO kit that includes 3 scales. Saved money by getting this kit for my PM-30'ish mill, and cutting the scales to fit, Actually, I only needed to cut the X-axes scale (cut down from the 750mm scale). Installation instructions leave a lot to be desired, but the operators manual for the DRO is very detailed. All the mounting hardware is included, but not very versatile. I ended up 3D printing brackets and spacers for a "better" fit on the scales. Build quality... no complaints. Display is large and clear, buttons are easy to read and use. Comes with a clear cover for the DRO. Powered from 110v outlet. Seems accurate for what I use it for (hobbyist). Although it could be much more accurate than what I am capable of measuring. On cutting scales, there seems to be two different methods out there. One where you take one end off the scale and cut the extrusion, glass and all. The other where you disassemble the scale, remove the glass and cut it separate. I used the latter method and had no problems. Although I did break a tap on one of the ridiculously small end cap screws. If I did it again, I would probably just epoxy the endcap back in place.
