Some feedback from our clients

I have a SINO DRO on my unmentionable lathe. It’s been on there for close to ten years with no problems. As to accuracy, I can’t say, except it’s got to be better than the lathe. My Mill has a 2-axis Mitutoyo DRO that does the job, but it’s not much different than the SINO.

SINO is the largest DRO manufacturer in China ,I’ve had a 3 axis unit on my BP clone for 12 years. It has been flawless and it is accurate.

The beauty of the SINO DRO units is the scales are interchangeable, I’ve had a SINO DRO display and scales on my mill for 4 years now, I haven’t had a problem with it
