£10.00 seems a lot of money for such a small bit of plastic and a couple of bolts, certainly not value for money in my opinion. But saying this, the product does the job perfectly, its secures firmly to my 25.4mm bars and also secures my lights, clamps very solid to bars and lights…no problems as of yet.
especially the front mounting bracket! If you have over sized handlebars 31.8 then the bolts are not long enough to fit through the bracket. I was disgusted that there was no longer bolts provided! Also, the front mounting bracket has an extending option, I needed to use this but once you extend the bracket the light just simply bounces about, ITS ONLY A MATTER OF TIME BEFORE THIS BRACKET BREAKS IN MY OPINION.
As for the lights, they seem well made, I have yet to try them fully and in the rain, but from the reviews I have already read I have a feeling once they get wet they will die...we shall see
