Amazing how many features there are on these economical DRO's. Bolt circle, find center, and many other features. They are very accurate also. ### ⭐⭐⭐⭐⭐ Nice upgrade to a Grizzly mill *by on Reviewed in the United States June 5, 2024* I ordered custom lengths (X/Y/Z=350/200/300) for a Grizzly G0463 mill. Increments of 50 mm only. This is a DIY kit with no instructions whatsoever. To get an electronic copy of the manual for the display, go to their website. Refer to the photos for details on the install. The scales have been accurate and repeatable, with easy on screen switching between metric and SAE. The read heads run underneath the scale, which keeps things cleaner, at least for the X & Y axis'. The included hardware, including scale covers are nice. I was able to use some of the parts, with the rest custom machined and 3D printed parts. I don't like that the read head is the same thickness as the scale, which requires you to shim the scale out to keep it from rubbing on a moving stage...a minor issue. ### ⭐⭐⭐⭐⭐ 5 out of 5 stars Value priced, meets or exceeds description, works as advertised and is a value. *by on Reviewed in the United States June 9, 2025* I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now.
