I came across this battery on the jungle site today, it seems to have fairly decent reviews, and the review meta website thought the reviews were real. What caught my eye was the price, 12 for $13. Cheapest i have ever found CR123 primaries. Anyone used these batteries? I found the Keenstone website, which is a bit of a wreck, otherwise I would have linked to it. Anyway, curious to hear if anyone has any quantitative data on these parts. I would be using them in my Olight S1R as a backup if necesary.
