The easy way to express our durability is to brag that we have sold over 2 Billion VCSEL-based sensors with the vast majority going into the cell-phone markets. I don't think too many electronics devices get dropped as often as cell-phones do.
We did do some Failure-in-Time analysis, but I don't think the statistics work out very well unless you have at least one failure when you over-heat and over-voltage the parts and run thousands of them for weeks and weeks.
We got no failures and the result of the analysis came out to several thousand years, and that's crazy.
Unless someone's life is at stake, I wouldn't worry about it.
