I've been looking for a lighting kit for my bike, I can also be mounted as a woman without much effort and especially lights, I can take off and put away quickly when the bike is somewhere unattended. This set of Sigma fully meets my expectations. The lamps can be easily with Velcro or elastic "mounted" and be taken back and fit into a small bag ladies. The workmanship is very neat and also the illumination is great despite the Mini lamp and the lamps look beautiful from sporty. Especially for a mountain bike will you yes no huge "Mutti lamp" :-) Super I also think that you can use the lights for all kinds of occasions (eg. Jogging or as a flashlight), because they are just not fixed. For me a top price-performance ratio and therefore 5 Stars!
