Got the lamp für`s jogging bought during dark winter evenings and am very satisfied. The lamp is characterized by low weight and easy handling. Makes a strong impression, even if the battery compartment is a little stiff and I only had fear cancel anything! From the comfort I was surprised had imagined uncomfortable. The rubber can be adjusted well and the pressure on the forehead is cushioned by the rear of the lamp along guided rubber, also to wear in autumn / winter usually anyway a cap or headband underneath. Did the first test run, the width of the rubber increasingly magnified because even with little train the lamp is fully seated. The brightness is quite enough to realize puddles and other obstacles in the brightest setting on unlit roads. On the sidewalks lit something dimmed setting is sufficient to illuminate the road still a little more and to be seen by other road users. My partner has at the same time buy the more expensive TIKKA Plus, I think the Sigma Sport can keep up here definitely for less money! Unique buy recommendation!
