Quality: Good quality product, solid metal construction with 200 x 5W leds. One thing to note is that the lenses are hemispherical and protrude slightly from the metal chassis. Design: Nice, simple controls, no fancy app so less things that can go wrong. Power pass-through works fine for connecting to another panel. Delivery: Fast delivery, got it in Ireland within a week of shipping from factory. Price is high though - a slower, budget delivery option would be nice to have Service: I timed the order badly right at the start of Lunar New Year, but Jack was helpful, explaining this and organizing delivery promptly as soon as the holiday break was finished.
