So good for such a low price, amazing.
Amazing quality,extremely well made and accurate. I do not know how they got the price so low. This is a fantastic deal I'm so glad I bought this item instead of one of the more expensive ones. I would buy this again in a minute and highly recommend it.

Repeatable, accurate.
I bought this for a stairway handrail project. It had all the features I needed. Measurements were repeatable. It has a zeroing button and you can lock the position of the arms. Also came with an extra battery.

East To Use East To Use
The Tirpheety Digital Angle Finder was a huge help on my recent project. I’m a novice when it comes to building, but this thing is so easy to use. It’s accurate and made measuring angles simple and stress-free. I used it to build a ramp for my elderly family, and it helped me get everything just right. A reliable and practical tool I’m glad to have. ... show more

Worth the money
While there are other angle finders available that are more accurate, this one does a reasonably good job. For the money, it works. The spare battery is also a plus.

Angles angles everywhere and not a drop to drink.
Perfect. Comes with batteries and an extra one I believe. Accurate readings of angles. Large, easy to read screen. Locks in place with a twist so you don’t lose your angle measurement. Lightweight and fun to mess around with. You’ll find yourself measuring all sorts of angles. What else can I say about this tool? Nothing. Works as intended. ... show more

very useful! Amazing price!
Works very well and is very useful for measuring angles to feed to you CAD program for 3D printing. Super inexpensive and surprisingly useful! Almost a must have tool. No case comes with it so I just 3D printed one real quick.

Weak locking knob
Knob broke quickly. I’m a person with very weak hands and I broke it by tightening the lock.
