I have to buy to P7 on the handlebars of my bicycle ride these holders ... so far so gut..der holder lies are easy to fit, the fit lamp, with some effort also into it, but as I before another holder of the same design have returned (see other reviews), I'm curious how long this now still holds. This holder is at the wheel of my wife and I have now switched to the hub dynamo and lamp Phillips. Yet he is keeping anyway, itself should change, undergoes this opinion still a while ... until then 4 stars
