On smooth surfaces, the lamp does not roll away. The holster was not used with me.
The brilliance and leveling is overwhelming when you consider running this part with two usual AA (Mignon) batteries. Ideal for walks at dusk or in the dark. For geocaching ensure optimal. Very compact and even fits in one, albeit large, shirt pocket.
With about 52 EURO certainly no bargain. So think twice before you need it.
A miracle also that one so hinbekommt a great quality in China.
Disadvantage: relatively heavy.
NOTE: If you can have it even bigger and it but extremely bright / wants to reach Fenix LD 41, which is powered by 4 AA batteries and only about 10-15 EURO costs more.
