I have to say the brightness and color intensity surprised me compared to my previous LED strip positive (what one might have expected with 72W actually, but still - wow) and would definitely be worth 5 stars if it were not for two downer: - The power supply generates a very ugly hum loop - "Self-adhesive" unfortunately does not mean that he also adhered well A plug connector with mains filter or create a Faraday cage around the adapter around creating unfortunately does not help and I in the part of the apartment where the strip is to be used, have no outlet that depends on another backup, I will probably again Must try other China power supplies, what the actual price for the use of the strip of course drives up again.
