Inclinometer, Digital Protractor/Level/Angle Finder and Gauge Tools with V-Groove Magnetic Base and Backlight - Dust and Waterproof IP65 Precision Smart Level（Not include battery）

Very accurate and works well. Great price.

Just what I needed. Makes setting the trailer easy.

This angle finder is accurate and does the job very well. The strong magnet in the base is useful, as is the bright digital readout. My only qualm (and this was fully disclosed in the product specs) if that the device is a little chunky, which makes it hard to use in tight spaces or with small parts.

This actually works. make sure you calibrate it. but hot dog I pulled this sweet little digital thingy out and what! It worked great. I teach a class that we need a basic tool for angles. this works great.

good quality

I'm very happy with this product. It's very easy to use and understand. Magnets on the bottom are very helpful. I bought it for my model train layout to measure angle of ascent, sleepless of the grade - rise or decent.

Good quality and strong magnet.

Worked as it should. Be sure to read directions
