Have the product before about 6 months erworben.Der shipping was very quick, everything Provlemlos! The lights make a very high-quality impression, the assembly was absolutely Problemlos.Ich some had concerns with a view of luminosity, this is all but expected to have excellent light individual super bright !! Shortly after the installation began, the lights on but not to go on, but by chance we noticed that they were not broken, it took some time until they adhered (5-10 min) then they shone with no problems! Since the dismantling would have been, however, a lot of work "planned" we this time with. This is irritating only if that would not shine like with us as subtle backlight serve but at night they are used for example of acute as path lighting. Since last about 1 month no longer experience this problem, however, on (no change to the installation!) The lights go immediately after switching on. What is negative and therefore only 3 * .... the customer service is written in lowercase, no response to e-mails by the seller ... whether we caught a Monday or production this problem generally occurs I do not know ... Bottom line I say, however, for this narrow money you get a very good luminosity in noble optics offer!
