This is such a cool tool! I bought it to use with sharpeners to set different angles to meet customer needs. It's very easy to use, very accurate and so easy to read! The display of this device really sets it apart from the rest. similar units. The display is completely black except for the green LED numbers and symbols, which ensures a very high contrast ratio. The image I've attached isn't entirely accurate, the glowing numbers are much more saturated green, the numbers are a bit blurry in the image. I will update my review if I have any issues with this goniometer. So far I'm very impressed!
