My Streamlight Microstream cap broke

I have a great little single AAA flashlight by Streamlight called the "Microstream". Well the little guy broke the other day. Nothing to major the light still works but, the rubber tail cap boot is missing so the light is not as water proof as it should be. So, I emailed Streamlight which have a lifetime warranty on their stuff. They emailed me back within a few hours and said a replacement was on its way. Once it comes in I will write a review on this light and show how to replace the tailcap boot.
