  2. An Exceptionally Well-Designed and Extremely Bright Flashlight! 5 Star Review

    Posted by on 18th Nov 2016

    The Thrunite TN40 is an exceptionally well-designed flashlight —not to mention, extremely bright and a very long distance beam thrower!
    It's also not as large as it appears in pictures, and strikes up a perfect balance in terms of it's size, weight, and very intuitive control switch —this, for single-handed operation.
    Furthermore —and the proverbial "icing on the cake", so to speak— is that one never has to worry about purchasing and changing batteries, as the TN40 is rechargeable and comes with it's own AC charging cord and adapter.
    Additionally, the inclusion of a multi-colour LED button, located on the tail-end of the flashlight, serves as both a power level and charge status indicator.
    Last of all, and typical to any and all Thrunite products, the build quality and fit-and-finish are top notch.
    So very well-done Thrunite! A definite 10 out of 10 product!
