First of all, super fast order processing and shipping!! 1.5 days from order to arrival. Plus very reasonable shipping costs. Replacing a halogen bulb unit that didn't last very long. LED light is super awesome!! Lights the whole pool. Although, red is the only colour that really does not light up very well. Otherwise, no issues. Lots of options for colour programs. Probably more than necessary, but one can find what works best for them. Remote takes a bit of time to figure out, but instructions included. I believe there is a memory with the on/off switch for previous setting. Installation was easy. Water must be drained to below hole if not off season. Good cord length. Solid unit. Would recommend especially at this decent price and service.
