  1. Jim (verified owner)

    A solid discreet torch with practical design and functionality. Moonlight mode is perfect for moving about in the dark and turbo mode is available instantly if required ( blindingly bright , moths from other countries would turn in mid flight toward your torch).
    Rechargeable battery gives remarkable longevity , months of non use and it remains perfectly ready to operate. Love it.

    Now this is a torch!

    Great quality & super bright, I love testing the turbo mode on mates once they’ve had a few. Very happy with the purchase.

    Great quality in a small package

    Taking into consideration the size of this thing, by far the best torch I have owned
