    I can’t say enough about the charger. I expected a plastic step-on-me-once-and-I’m -dead charger. This thing is tough! I don’t know what it is made out of but I am so impressed I’m getting one for my step-son.
    I use mine (HL60R) professionally (daily) and made the mistake of taking it goose hunting once and my step-son really loved it. He got one for Christmas and now getting a charger. Inexpensive and sturdier than any charger I have ever purchased at any price.

    Friends gave me a Fenix UC40UE tactical light for my birthday, and I am hooked on Fenix Quality. Just returned from a 12 day elk in the Wyoming back country and this light was outstanding, while using the FENIX 3500 amh rechargeable batteries. 900 Lumens from this small compact light it awesome!! Outstanding quality!! I just ordered the new version of the TK75 and cannot wait to get my hands on this one. Fenix service is also outstanding and they are always helpful when I call…. helpful and full of the correct information! Keep up the good work! Fenix quality is second to none!!!!

    Just got the batteries, they look good and are charging now. This review is primarily for the Fenix brand and level of service. I ordered two of these batteries and a two Bay charger. When I received the order there was a 4 Bay digital charger and a note stating that they were out of stock on the two Bay and to please accept the free upgrade. I am highly impressed, Fenix didn’t have to do that but rather than make an ordeal out of it they not only got me what I needed but gave me more than I had asked for. I appreciate this greatly as I am going camping in a few days and don’t have time to order another from somewhere else without having to pay overnight shipping. Fenix quality is outstanding and they’re service to customers matches it. Im now a customer for life
