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 after about 100km. on the bike tour of 1000km broke a clamp at the base of the rivet in half ... very unfortunate ... well returned, get money back and all was well ... the dealer was super, the product not :-(
