Ok, I saw the words "internal mechanics" and took that as a reference to the gyro. For the outer housing, we know all inline pucks have failures, so we expect to be competitive to the most popular pucks on the markets.
We were very aware of the abuse the puck would take. So before we launched we created some unusual tests to evaluate the internal parts: https://www.facebook.com/610421699096174/videos/2392684927433016 The video shows 1/2 of the gyro being tested. In field tests, so far, we haven't had any gyro failures reported.
