I have been using Fenix lights since they were only 1 watt LEDs running off of 2 AA batteries. I have been upgrading as each successive generation becomes available. So far, I have not had a single issue with any of their lights. I just received a TK-30 and love its form and function. It fits perfectly in my old Streamlight Stinger holster perfectly. All of my older hand me down's are still in use and without issue. I have recommended them to several people at work whom also currently use Fenix lights without issue. My one bit of advice is that you maintain your lights. Clean the contacts and lub the threads at regular intervals.
