I had a friend help me with some wood working when he pulled out this little box that told him relative angles. My mind was blown! This one has been incredibly useful and I’m beyond happy I splurged on something that seemed frivolous.Overall the build quality is decent. It feels a little plasticy, but solid enough. It’s light and has a magnet on the bottom that’s decently powerful enough. I’ve accidently left it attached to the sheet metal of my Sprinter and drove a few hundred miles without it falling off.Accuracy is pretty decent. If you’re looking for .1° precision this isn’t it. The screen could also have a better viewing angle and a second axis would make this a killer tool.Would definitely recommend though, especially for the price.
