I have used this digital sensor before but ended up liking it a lot more. Contrast is very legible with no reflections (an issue with my last one) and this one was about as accurate as I'll ever need. At first I didn't know why the accuracy had dropped to 0.1 and the resolution to 0.05, but after using this I really like sneaking up on the exact right angle. I'll never need an exact angle more than 1/2 degree, but this one will handle anything I'll ever need. I was pleasantly surprised by the solid weight of the sensor and that it already comes with batteries. I have used this company for other products and will keep them in mind for budget tools in the future.
