Cen-tech (HF) Digital Angle Gauge

I have been wanting a digital angle gauge to compliment my newly rebuilt tablesaw. The Wixey WR300 Digital Angle Gauge is $40 everywhere, so when I ran across the Cen-tech Digital Angle Gauge while browsing at my local HF, I figured "what the heck, it's only $30." Normally I am very wary about items purchased at HF. I think this was a good buy. It's simple, easy to use and dead-on accurate. My only complaint is that the magnets in the base of my particular unit are recessed too far to make a strong grip (it slides sometimes).
