For now we have not sufficient. Primarily we wanted a flashlight at night to find our black dog in the dark in field and meadow again. This lamp is to completely unsuitable. Although Fits in your pocket, but no lights 10m wide. Add to this that they are the front one on a rotation principle at the beam on and off. Incredibly awkward and we constantly had loose contacts. Certainly suitable for lighting of things that are in close proximity. Maybe even for dog owners who run their dog on a leash and not disturbing sounds 2m. The rest I advise against this maclight and recommend the maclight 2D Cell LED lamp. Positive aspect is still the return. Went without any problems!
