Here are already buying some LED at the end failed (I have simply cut off), then later in the failed operation, some in the middle. While still working, still annoying. Replacement was sent to me immediately.
the great advantage of the bars: There are corner pieces, power supply and connectors included, so you can even make his "Leistenweg". But beware: If one has a first LED strip cut off on one side, the connection is only possible if one solders itself.
All in all, a good product is not very reliable at a fair price, unfortunately.
Power consumption: Ca. 15 Watt
