Just thought I would pass along this information pertaining to Stringer flashlights.
I own 2 ultra stringers. Both off them the on/off button has wore off the rubber and many times gets stuck in the on position.
I was looking to purchase yet another one when I inquired with Streamlight I was told that the body & switch have a lifetime warranty.
Basically it will cost me shipping fees, but saves me the cost of a new light.
Hope this helps in saving someone a few dollars.
I still may purchase the Nachi stringer as it would be nice to have one.
