Well, we know the DeWalt design is good. Not as well constructed as the Lamello brand ones, but certainly sufficiently well made.

I have never (in 10 years) used any settings other than 0, 45, and 90. But were I ever to use the "in between" settings, I would not rely on the degree markers regardless. Instead, I'd just wrap the fence around the item(s) being joined.

Cheers
