I didn't order mine on amazon, but these are good products. I'm no expert at measuring their quality, but these smart LED light strips with music synchronization have been serving me for a year now, so they're pretty durable. They don't flicker, are waterproof and heat resistant. I accidentally tested that last point by spilling hot coffee in my car. I was afraid they would stop working, but nothing changed. My wife says she needs some extra lighting in the living room to add more ambiance, so I'm even thinking of installing some of these lights in the house. I want it to be a quality piece. I hope my suggestion was helpful.
