Bad at the one thing it needs to do
After zeroing, it’s off by 0.35 degrees at 90 - compared against multiple framing and engineering squares. That’s more than 1/16” per 12” - more than enough to be very noticeable. Would not recommend.

5.0 out of 5 stars Easy angle measuring
Reviewed in the United States on August 24, 2012
Verified Purchase
The 7" digital protractor makes it easy to measure angles and has excellent features. It seems to be a well thought out design.

- good size for fitting in a tool box
- LCD screen is large and easy to read
- easy to reset the measure to zero at any point
- can be set to hold a measurement on the screen with the press of a single button
- the display turns off automatically after a while to save the battery

The knob at the pivot point can be tightened and loosened, but it would not actually lock the angle in place. It does get pretty snug and holds the angle well if you need to physically transfer that to something rather than using the digital measurement.

I've only used this for one small project so far. That was for measuring the angles where the joists for a ramp into a shed (for my mower) meet the floor joist. I was rebuilding an old ramp and could see the old cuts I made the last time I did this, years ago (I was able to re-use much of the lumber). Using this protractor made that process much easier and more accurate than it was before I had this tool.

5.0 out of 5 stars Great tool! Great value!
Reviewed in the United States on January 9, 2015
Verified Purchase
This is a great tool at a great value price. It's the best protractor I've ever used. Easy and useful. I checked the accuracy of this device and find that it is ALMOST, but not quite, up to the guaranteed 0.3 degree accuracy. After carefully zeroing the parallels against a good flat, and checking it against a machinist precision 45-degree angle, this device reads 44.8 degrees, which meets the specifications. But checking it against two different machinist precision 90-degree angles, against both it reads 89.6 degrees, which exceeds the specified accuracy slightly. This doesn't trouble me very much, however, because I intend only to use it for woodworking. And if I have to check an angle with better accuracy, i can apply a correction factor after calibrating the deice against a machinist precision angle. I don't know any kind of protractor that can be read more accurately than this one. It also does shut off automatically after about 3 minutes of sitting idle, which is handy to conserve the battery. It came with one battery installed, plus a spare battery. Highly recommended.

4.0 out of 5 stars Accurate gauge at a fair price
Reviewed in the United States on February 9, 2016

I have purchased two of these protractors about four months apart from Amazon. I keep one in my shop and the second one in my tool box. The vendor has changed packaging between my purchases. The new protractor came with a spare battery and a protective film on the arms. Maybe the first purchase was a return, but it works fine and the arms were scratch free. I'd like to think that the vendor improved their packaging. The installed battery on my second purchase was dead. The spare battery saved me a trip to the store. At least the protractor uses a CR2032 which is widely available. The battery is a pain to replace. The battery compartment has two thin plastic tabs that are difficult to grab without fingernails or a thin screwdriver. I hope that I don't have to replace the battery often. The protractor is large enough that it can't be used in a tight spot, but this limitation is obvious from the description. Some angle guides measure to hundredths of a degree; this one measures tenths of a degree. The instrument resolution is good enough for me. The only complaint I have is there is no button for a complementary angle. Measuring for a miter I sometimes move the wrong leg and have to do the math myself - not a big deal.

Hi Temp User
5.0 out of 5 stars Good value for the price.
Reviewed in the United States on April 26, 2024
Verified Purchase
Bought the 4inch version for general hobby level metal work activities.
Digital readout is smooth and monotonic as the blades are rotated, and don't jump around, which was pleasantly surprising for a low-cost instrument. The range is a full 360 degrees.
The blades are stainless steel and clearly graduated up to 64ths, and the assembly is reasonably well made, edges deburred and clean etc.
Repeatability rather than absolute accuracy is the strength of this instrument for this price point, so when measuring an angle and reproducing it at some other time, it's pretty good at around 3 arc mins. For setting an angle, it claims +\- 0.2 deg absolute, so better than a cheap hardware store mechanical protractor where you might be lucky to get around 0.5 deg (depending on eyesight! ), but definitely worth thinking about what you want this for up front.
Only issue found is that the pinch screw does not lock the blades very tightly.

3.0 out of 5 stars Finicky!
Reviewed in the United States on January 28, 2022
Verified Purchase
If this thing is used carefully with multiple checks to verify the reading, it is usable. The problem is if you ever change direction, it loses accuracy by a tremendous amount. That means if you open it up to a certain angle, and then close it to a smaller angle or vice versa, the reading will be off by a really significant amount. But if you tighten it down and open it slowly and carefully to the reading you want, it will be quite accurate. The problem is you can't trust it until you've checked and rechecked three or four times.

5.0 out of 5 stars Easily worth the price.

Highly accurate. Tested against a set of standard triangles as well as custom made forms (various star jigs, polyhedrons and shapes) and this device is repeatably accurate to its stated 0.05°. Hefty for its size, this is no feather-weight chunk of plastic junk and easily holds its angle even without tightening the tensioner. I am VERY pleased. Love the big digit display - it's nice and easy on my older eyes. With my glasses off I can read the serial numbers on a gnat's ass, but this lets me keep them on while I wear a face shield and measure / cut on the fly.

This is a substantial and useful tool that can be had for a good value price. It is not on a par with Starret or other high end gauges for accuracy to the finite degree, but at its price point it is more than satisfactory for woodworking and general measurment. Fast delivery and appropreately packaged. Satisfied and would recommend the product for others.
