I bought about 2,500 Inova Microlights to fill a military order for our survival kits and 5% of them were worthless. Some of them had dead batteries, others would turn themselves off and on when you bumped them and several were shipped to me without the batteries in them. The good part was that they replaced all the bad lights- no questions asked.

We have purchased several thousand Photon II's and we just found the first bad one about a month ago (the batteries were low). It was also replaced with no questions asked.

The great thing about owning a survival kit business is that I get samples of just about everything you could ever want in a kit and I have tested just about every microlight available (I have a box full). I have yet to find a worthy replacement for the Photon.

My 2 cents, George
