Ultra Small Digital Angle Finder Magnetic Level, Rechargeable Angle Cube, Table Saw Miter Gauge, 4 * 90 Degree Protractor Electronic Inclinometer, Wood Working Measuring Tool

Great accuracy and battery life. I use this for levelling my tripod and setting the initial angle of my equatorial wedge (used with a star-tracker). The angle readings on this unit matched that of a similar inclinometer (but different brand) to within 0.1 Degrees. Note that the readings on the display update fairly slowly, so one must be patient if trying to do fine adjustments to the angle of your workpiece.

Very small, seems accurate enough for me. I’m using it to set the angle on my knife sharpener. Magnets work. Decent price. Happy overall!

does what it says

The magnets were not strong enough to stick to the surface that I needed!

Works ad advertisements and I really like the magnets

Product has worked well with first uses. I was looking specifically for an angle finder that was on the smaller side, happy with what I received!

Average.

I bought this to measure angles on my sheet metal bending brake, and it works well for that. However, I have found MANY more uses for it. I do a fair amount of welding, and don't have a dedicated, level, welding table, so using this digital level to verify relative level and relative 45/90/whatever degree angles is fantastic. I just put it on the reference piece, zero it, and then setup the sevond piece to whatever angle i need. I can't verify it's accuracy, but for me it seems to work very well.
