Here's my experience with Fenix. I have a TK11,LD25 and a E21. I bought the TK11 for a weapon light that's on a gun in my safe, I think I've turned it on maybe a half dozen times to check to see if it's working. It works only because it's not used.
The LD25 worked for about six months and then one of the modes stopped working. Sense I bought these on line directly from Fenix, I sent it back under warranty for repair. Long story short, they had to send it to CHINA for repairs. After nine weeks I finally got it back. The absolute worst customer service I've ever seen in my 55 years.
The E21 was my wifes light. This light is about eight months old. It gets so hot that it corrodes the battery's within a couple of weeks. She told me the other night that it stopped working. After messing with it for awhile, I threw it in the garbage.
I hope you guy's have better luck with yours!!!
