I had the opportunity to use this sensor and it turned out to be very useful. In the past, to find the measure of an angle you had to guess, or at best it was close. Now with a digital angle sensor there is no guesswork and it is accurate. The ability to reset doubles its usefulness. In addition, the presence of a convenient carrying case allows you to wear the sensor on your belt. Overall I love this product and would recommend my friends to get their own.
