  1. My new favourite light 5 Star Review

    Posted by on 15th Mar 2021

    I bought the MK37 from selected-lights.de

    My conclusion: Manageable size, ergonomic and good looking design, great brightness and throw, and a very good regularization made the MK37 to my new favourite flashlight. The userinterface is very traditional, but OK .
