I am fully satisfied with the product. The backlight can be easily mounted to and the device and remove the radiator is smooth but trotsdem safe. When the batteries are running but you have to be a little careful, because the case is not screwed but is held together via a click mechanism. Personally, I think the better, because I constantly the screws broke in my taillights. A word to the luminosity. "Super Light" is a bit exaggerated, but they are all bright and the batteries should last quite long. For the price: strong buy recommendation on my part
