"I am a hobbyist woodworker, and I've (been) after one of those protractors for months now. Every woodworker should have one in their toolbox because no house has got exact 45 degrees corners. If you are a pro or a diy person they are a very handy tool to have, but one tip make sure you're mitre saw is bob on by using a square before you start."

"Really good item, well made. It is fairly expensive for what it is, but does a useful job when measuring wall angles."
