Overall, I like the product very well. The almost 90 EUR Amazon are unbeatable in comparison. The installation is a bit fiddly, total connections are already of billigster quality. Sorry upfront always small gaps that I did not wegbekomme. The spots partially made of metal and for the price really OK. I take the supplied GU10 halogen spotlights other GU10 LED spots fitted, so that the lamp looks genuinely futuristic well. The connection cable I had to cut back, because it simply was too long. No problem, you have to just before mark the earth, because all cables are the same color.
Conclusion: High and processing technology not bomb, but perfectly adequate for the price. You can also pay tenfold for a rail system similar optics (!).
