Review on LOFTEK Submersible LED Lights With Remote RF(164Ft),Full Waterproof Pool Lights For Inground Pool With Magnets, Suction Cups,3.35” Color Changing Underwater Lights For Ponds Battery Operated (4 Packs) by Brian Edwards

I love the lights themselves, and that they don't require a traditional power source. But expectations need to be managed up front. The suction cups don.t work that well. So I honestly just toss them into the pool and let them rest where they will. Also one of the lights not long after use decided it wasn't going to respond to the remote control. I removed the batteries, put them back in hoping this would reset the light, but no dice. Anyway they're cool, and its awesome to have the color changing lights at night, so no we move on.
