Excellent tool for eliminating the guesswork for angle cuts. Great tool!

Very pleased with the digital angle finder purchased. It is made of quality material. It is accurate & easy to use.

Seems to measure angles ok but the instruction manual battery replacement instructions are wrong. There is a screw on the back of the tool (where you would not see it when the tool is closed, which is the normal storage configuration) which must be removed to allow the battery compartment to open. Rather than update the manual with the proper information they added a sticker to the back of the tool (again where you wouldn't see it in the normal closed configuration) pointing to the screw. Please update your manual to be accurate!

Works very well!

The quality is absolutely the best , easy to use and zero out , weight is light but quality is there , function is great

I compared two Digital Protractor Angle Finders: "S&F STEAD & FAST" & GemRed (2 black button version). I was hoping for a clear winner to make my decision easy, but I did not get that.Commonalities: Both brands are made in China, use the same battery, & are the same length (400mm, ~15.75 inch when fully opened). They both keep the battery in a no-tools-needed, easy to open "drawer" so it's easy to remove the battery to prevent battery drain during storage. I won't be using this every day or even every week, so this feature is important to me.Build Quality: Both rulers are the same thickness of SS (Stainless Steel), but they are different types of SS. The S&F is attracted to magnets and the GemRad is not. (There are over 50 types of SS & some are attracted to magnets.) Since they don't say what types of SS they are, I give the edge to the non-magnetic GemRad.The S&F has thicker sturdier plastic (especially the battery drawer). The GemRed battery drawer opens a bit too easily (if jolted, the drawer can open & the battery can disconnect). The S&F battery drawer opens stiffly.Finding Angles: As it should be, the GemRed angle ruler is easy to move when the lock knob is loose and it gets stiffer as the knob is tightened. The S&F however, is stiff to move no matter how loose the knob is. That would be a disadvantage when I'm measuring angles of things that flex when I push on them. Turning the S&F knob very tight makes in only a tiny bit stiffer.Ruler: The S&F ruler markings are darker & much easier to read. The metric markings on both brands go from 0 to 400mm. As you might expect, the S&F inch markings go from 0 to 15 & 16/32. Inexplicably, the GemRad imperial markings go from 0 to 7 inches, twice (instead of a continuous 0 to 15.5")! IMO, GemRad fell down on that one.Buttons: A quick press of the GenRad [On/Off] button only turns off the display, while the rest of the electronics continues to invisibly waste the battery (unless I remember to hold the button for 3 seconds). I don't like that. The S&F has 3 buttons & more functionality than the GemRad. The S&F has a [Hold] button, which could be handy in a situation where I can't see the display while measuring some angle. The S&F also has a button to display in degrees & minutes, instead of decimal degrees, but I doubt I'd ever use that feature myself.(The GenRad has some "hints" on their instruction sheet. One is "Never leave it outside in a wet and shiny environment." Another is "Do not use as a weapon to hit people." That seems like good advice -- a rock would make a better weapon.)I went back and forth about which one is better for me. The S&F is better than the GemRad in so many ways; however, I could not get past the S&F angle measure stiffness and non-functional lock knob. Since I plan to use it mainly to measure angles (not as a ruler), the GemRad is better for me. I'll have to remember to use the battery door as my On/Off switch.

I’m impressed how well this works. Many higher priced units on the market that don’t work as well. Glad I bought it.

Haven't used it yet.Well made.
