This thing is very accurate and easy to use. The built in magnet is strong unlike others I've used. I'm an electrician and bend conduit almost every day and this inexpensive little gadget sure makes my job easier.

This is a handy little tool that I wish I had purchased a long time ago. Works great for a lot of uses and especially when you are sharpening knives.

Great little angle finders. I use these with Paco Motorsports hub stands to align my cars. They seem to be accurate to 0.1 degree without any issues. Be aware that magnets are only on one surface (bottom). The display does auto-invert if it detects it is upside down. Work well. I've dropped them a few times and they still seem to work OK (seem durable). Easy to read with the backlighting even in the sun.

Wanted to make sure my table saw guide for angle cuts was accurate. Fortunately for me, my gift and this level finder agreed. Works easily, just set on your table saw surface, press button to balance to zero, then attach to saw blade.

Magnet not strong enough to attach to a standard blade, makes it a little harder to enjoy than it should be.Mine seems very accurate and I used it to set up a new Miter saw. So far so good. If you want to use on a table saw you may want to get one with a magnet strong enough to stay on the blade.
