at the beginning very well, unfortunately only brief functionality

I had 3 sets ordered a 5 LED. The first set went right back after 2 LED were broken after about 1 minute.
The exchange went but reibunglos. However, I had to send every 5 LED.
The light output is subjectively very good.
Now, after 3 months 2 more LED are faulty and begin to mehrminutiger burning time to flicker, and the annoying!

I now try a Untausch. But perhaps man ought to have recourse to a German, more expensive product, as these Chinese goods.
