Brilliant. Simple to use. Very easy to use and self explanatory. Certainly accurate enough for what we are trying to achieve when setting up a heli, and seems to be as accurate as a normal pitch gauge on heli with flybar.
No instructions Not intuitive. No instructions included. Web page link doesn't work (404).
Not very useful! Seems to be very out dated, only calculates values and not measure!
