I can not see the field most of the shortcomings in other reviews in my personal (usage) - which, for example the holder concerning perhaps is also due to the different bikes / handlebars strengths etc. Bin with the quality, durability and the luminosity (even at night) very satisfied.
Only I have to complain that the light now, after more than a year of regular use to previously relatively quickly charged the "juice" in relation loses. Hence only four stars. Because that would not necessarily occur yes. Should the further change to negative, I will this grudge here.
Otherwise - I drive a lot in difficult terrain, was already several times mountain biking with this lighting set - I had what lt the holder or other defects so far no problems other reviews relates.. My lamp holds bombproof on the handlebar and is once dropped in a fall. To date, I have not had damage such as broken parts or the like.
In this respect, I can absolutely recommend the lamp itself with a clear conscience.
