Review on DenicMic Firework Lights Starburst Lights 200 LED Copper Wire Battery Operated Hanging Sphere Lights with Remote - Illuminate Your Patio Party Wedding Christmas with 8 Modes Fairy Ceiling Decorations (2 Pack) by Diana Cardonne

They are bright, colorful, very animated and fun to look at. They are also very energy efficient. A set of alkaline batteries lasts more than two months. The timer works correctly. And they remember their attitude when the power is turned off. One of them had its cable come loose and stopped working. But I won't blame the product as I have them outside and the wind tends to blow them around a bit. It was easy to remove the plastic connector holding the fired wire and re-solder the loose connection. He's back to work. The battery compartments on them are fairly waterproof. The electronics are well protected.
