Review on Koxly Fairy String Lights USB Powered - 16 Colors Changing, Waterproof, 33ft Twinkle Lights with Remote Control - Ideal for Bedroom Christmas Decorations by Julie Jones

Remote only works within 3-4 feet with line of sight between transmitter and receiver. Some keys take 5 or more tries or just don't work. If you select a color, these are only available in always-on mode. When one of the four modes is selected, all colors are used and there is no other option. All four modes are basically a temporal variation of a line flashing in unison, and aren't necessarily associated with a label on a key. The LEDs are so big that only three primary (RGB) look right. All mixed colors are heavily soiled and shifted away from warm tones. The white setting is so high in the cold range that your eyes will beg you to change it. They just aren't worth the price. Two strings were enough for a 30 inch tree.
