I purchased the Wuben E7
I purchased the Wuben E7, a battery extension and extra battery that all worked great…until the batteries went dead. As with others in the reviews, the flashlight will not charge with or without the extension tube. I also purchased an entirely different battery, but it won’t charge either. Sadly, the 30 day return policy ensured that I can no longer return this item. Beware, if you choose Wuben products! I would recommend other manufacturers.
