Watch out for FAKES!
Color: 7" Yellow & White
There are likely quite a few fakes in circulation from Amazon and elsewhere. I ordered one from a third-party seller with fulfillment by Amazon, but upon close inspection after receiving the item, it turned out to be a fake. I purchased a second that was actually "sold by" - not just "fulfilled by" - Amazon and from inspection I'm sure it is genuine. Please see my photos with the details. The fake was very close in almost every way. Without a real one next to it, it was a challenge to identify. If I had bought it as an off-brand out of a bargain bin, I probably wouldn't have had any complaints. It still looked pretty functional. I wanted the real tool for this though; I just couldn't get past the concern that I would end up with less precise finished miters and/or more rework with the fake. The fake I got appeared to be pretty close on accuracy though. Differences: Laser Engraving- Real has true laser-etched dial with consistent alignment of markings and numbers. The laser actually "digs" tiny trenches with a little roughness at the edges of each engraved "trench". Feels a little like sandpaper when sliding finger across markings. Fake had some sort of printed markings deposited on top of the surface with some of the digits poorly aligned. Markings could be felt, but were much smoother than laser engraved. Would expect less precision in this method of manufacture. Fit & Finish- Real has a bold yellow inlay with a precise geometry that lays in flush as intended. Fake had a little more drab, somewhat translucent, yellow inlay with less precise geometry that didn't entirely lay in flush as intended. Could just barely see some the structural ribs in the plastic behind the yellow inlay on the fake because of the inlays translucency. Pivot Screw- Real has a pivot screw head that is ø0.65" (21/32") [16.5mm] in diameter. Fake had a pivot screw head that was smaller at ø0.60" (19/32") [15.2mm]. Package- Real had a Proposition 65 warning sticker on the back and was not stapled closed. Fake was stapled closed and did not have a Proposition 65 warning sticker. Printing on fake was extremely close to that of the real article. Fake happened to have some barcode stickers on the exterior, but still had the same original barcode inside the package. Some of the details may be different on other fakes. These are just the most discernible discrepancies I noted on this specific fake. My rating is based entirely on the legitimate product I received, not on the fake.

Versatile tool especially good for crown molding
Color: 7" Yellow & White
This is an excellent tool, especially for someone with no previous experience cutting crown molding. Step-by-step instructions are included, showing what bevel angle and miter angle to use on a compound miter saw after the measurement from the tool is known. The scale is easy to read, and the plastic body is sturdy but light weight. The tool can be used for a wide variety of measurements beyond crown molding. A few dollars invested in this tool could save a lot of trial-and-error aggravation, not to mention wasted material. Highly recommended!

No batteries, compact
Color: 7" Yellow & White
Great compact angle finder. Out of box was less than 1 degree off. Good for rough carpentry. It will be hard to find precision for the price. Again know your application. Better than a standard square in certain applications. The fact no batteries is great as well.

Makes Measuring and Cutting Angles Much More Accurate
Color: 7" Yellow & White
This Starrett miter protractor is one of those tools that quickly becomes indispensable if you do finish carpentry, trim work, flooring, or woodworking. Instead of trying to guess or manually calculate angles, you simply match the protractor to the corner and it gives you the exact angle needed for your miter saw. It saves a lot of time and helps eliminate costly mistakes. The laser-engraved markings are easy to read, and the tool feels solid and well-made. The pivot stays tight while still moving smoothly, allowing you to transfer measurements accurately without the angle shifting. It's especially useful for inside and outside corners that aren't a perfect 90 degrees. As expected from Starrett, the quality is excellent and built to last. Whether you're a professional contractor or a DIYer tackling home projects, this tool makes achieving precise miter cuts much easier and far less frustrating.

2 saw settings with one measurement
Color: 7" Yellow & White
Wanted this tool to help me get the angles for a box type valance on a bay window. It did the job and the best part was that it told me the angle at which to set my saw for the mire cuts. At the same time it told me the setting for the part that met the wall. Those two settings are on an inner and outer scales of the tool-one measurement, two different cuts! As a novice I thought that the guage was quite accurate and the pieces matched very well. Unfortunately, other parts of the execution of the project were faulted. The tool itself needed to be tightened substantially in order to maintain the measurement but that was easily done with the "screw" on the backside . Well worth the price for me

Simple effective tool for cutting miters
Color: 7" Yellow & White
The preferred tool to cut miters when doing trim work in a house. it is a bit smaller than I expected. I got the idea to get this from a youtube video There are some other options, but this is the simplest and most effective. You can set it to match either an inside, or outside corner angle, and you can read the half-angle off of the tool (it has an arrow that points to it) . I used another tool first, then I bought this and fared better with this than I did with the other tool.
