Order fulfillment was excellent. The product is terrible. With 300 LEDs, I expected a strip that was luminous - i.e. bright when turned to white. This 5m strip uses more power (I tested it in a smart plug that measures watts being used) and puts out less light than a 2m Philips Hue strip. LEDs are not all the same. These are cheap and nasty ones. Sure you can get red light and blue light and green light and it is a great toy. It fails as a professional proper residential efficient product that gives you 80 - 100 lumens of white light per watt of power then you are out of luck. Very disappointed. Sending it back. It isn't worth the candle (use Google to look up this saying as it's quite old).
