Perfect product for my DIY projects that we do around the house in our spare time! The angle measurement tool is made out of plastic, but I will say that it is sturdy. I think the plastic ones are great for occasional use, but I would recommend metal if you are planning on using it on a daily basis. The markings are easy to read and see which is a huge plus if your eye sight is not the best. I am pleased with my purchase and it has made measuring a lot easier!
