I have used the Tank 007 E09 for several months, and it has become my favorite edc. Looking on ebay the lase month I have seen other T007 lights, and have purchased the PA01, PA02, PK 307, and TK 566. They appear to be a lot of “Bang for the Buck” to me. Not sure about the longevity, but so far so good.
I have some of the single modes on order. I find that sometimes a single mode works better for women who are not interested in lights, and just want something to see at night. Of course, the AAA lights on high have a short run time, but this AM I had a PA01 run almost 1 1/2 hours on a Chinese made alkaline battery I was surprised at that run time.
