I have lost mine a couple times, and found it no problem. It came out of the case once and bounced off the track into the weeds, and I only lost the memory card. It still works fine in the zip tied case even. You have to grab three hundred fifty dollars, crumble them up, and throw them over your shoulder before mounting it the first time as a gesture. If you do you'll be fine when it gets wasted in the first practice session. Oh and I learned that the curved style mount bracket typically used for helmet views of yourself will not take the vibration or force of being mounted directly to the bike, and will break if you ride fast enough.
