Outus Angle Protractor Angle Finder Ruler Two Arm Stainless Steel Protractor Woodworking Ruler Angle Measure Tool with 0-180 Degrees (30 cm/ 11.8 Inch)

Good

I read all the 1- and 2-star reviews...I'm not sure what the heck those folks were expecting for $11. Yeah, the edges were a bit sharp...I spent two minutes running a fingernail board over the edges, now they're smooth as butter. Yeah, the knurled cap-nut was a bit tight as shipped, but no real problem. Yes, the cap-nut didn't tighten down enough to hold the swing-arm securely (the threaded hole is a bit too short), so I added a tiny washer on top of the compression washer, and now it holds tight. They said the tool they received is inaccurate...but I found it to be within half a degree (or less?) at 25°, 30°, 45°, and 90°. The small size of this protractor doesn't really permit measurement to tighter tolerances than that. One guy said the angle was measured wrong, "...The middle of the ruler and not the edge is where the angle would be accurate." Say WHAT?! As long as the edge of the swing arm is parallel to an imaginary line down the middle (which it IS), then the angle is always going to be the same, whether measured at the middle or EITHER edge of the swing-arm. A couple of folks rated the protractor low because it wouldn't measure inside angles. [sigh] If you want to measure inside angles, buy the right tool. You can get a plastic goniometer for under $8. You can buy a digital angle finder for as little as $17 (although I'd likely shell out twice that and get the Klein). If you want to stay on the cheap, and you already have this little protractor, use a sliding T-bevel (or even just fold a piece of paper) to match the inside angle, then use the protractor to measure the outside angle. But don't criticize a tool because it won't do something it was never intended to do. Look, I'm an amateur woodworker. I buy and fettle old chisels and planes. I use a honing guide to set the initial bevel (25°) for the cutting edges on the chisels and plane irons. We aren't looking for crazy precision, we just want to be consistent and close enough. This little tool is exactly what we need.

Nice addition to kit

GOOD PRODUCT, STRONG DESIGN; HOWEVER, USER MUST MAKE MINOR ADJUSTMENTS TO KEEP THE HANDLES IN FIRM POSITION FOR MEASUREMENTS.

Worked a treat, easy to use if the side is the correct way, but in tight spaces, sometimes couldn't measure angle duento size of the protractor and orientation

works as expected ,edges a little bit sharp but still for the money ok .
