I am very happy with the digital protractor. I was really looking for something that would show me the angle on my table saw as my table saw scale is not that accurate. But I've found many other uses for it as well. And the fact that it's magnetic is an added bonus. I make wine racks and to make sure the metal tubes line up perfectly I can use this now. Delivery and support are always first class with Mecurate. This is a must in my opinion!
