I just returned from a customer that has had some sensors failing; specifically the circuit boards inside the Lynx case have failed.

Right now the Lynx sensor case has some shock protection in the transverse direction but less or none in the other two. We are working on this problem but it is not finished yet.
In the meantime, until we can shock protect them in all directions:
