Even though my Hawkeye borescope was protected in the expanded foam inside its box, when I bumped the box and it fell to the floor it found its way out of the box and into the base of my drill press. Result = broken mirror. 
So I tried to order a replacement mirror. How hard can it be to epoxy a little mirror at a 45 degree angle inside a metal tube.
Order one? No can do.
So the only way to make it like new is to send it back to Gradient Lens Corp.
Their charge = $85 :'(
Shipping is, of course, not included.
If you own one of these things be careful with it (might even want to insure it)
