For the Sigma I decided since they are small, lightweight, waterproof, good-looking and is easy to assemble. More than 12.000km has now been with me the HIRO. To burn time, I can confirm the specified 60 hrs. Approximately. The handling is simple: as long as the HIRO indicates no red ring on the switch, but white or green one need not to make a battery replacement care. And the Emergency running time is approximately 2 hours. Sufficiently to come from a smaller tour home safely.
Take the HIRO switched even during the day, because it gives me a good feeling of security. Both Belgian cycling not cobbled and tours Cross has so far unscathed the HIRO. Other reviews, reports of defects and fall of the light, I can not understand. It is true that the opening of the HIRO with a 10 cent piece best works. With careful levers and without use of force succeeds almost always non-destructive open the tight-fitting housing me.
The HIRO has so convinced me that even the racing of my daughter and my wife got a Crosser HIRO. For this reason, I always have a small battery supply of rare Battery size (s. Description) at home. Today I buy my 4 HIRO.
