    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    GREAT STAMINA

    posted by emilcho86 on 12/27/2012 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    I ordered 4 of them, all worked ok, they arrived already charged (half capacity I guess), and they've been running for 1.30hs on a 500lumen flashlight I suppose after a full charge they will boast my light up to 3 hs without problems.
    Cons:
    None, maybe they could be prettier or a little bit sturdier but that's just an impression, they work just fine, and arrived in ...
