Great lights but if you are new to these wire fairy strand lights, don't be overwhelmed trying to unravel them and then get them knotted. If you're patient upon opening and follow the way they were wrapped for packing, it's very easy. I've done both ha! They are GREAT. They have usb so find a spare cube laying around to plug them in and use the remote to select light flashing mode or steady, and to dim or brighten them as well as turn them on and off.You can do everything except dim, without remote, with the push button built into the USB .What I love most about these is they DO NOT GET HOT or waste electricity. I use them above my kitchen cabinets, around my living room and bedroom windows and fireplace mantel. Gives a beautiful warm white glow without the bulky cords or heat produced by ordinary Christmas style strand lights. Less of a fire hazard too!! They last a LONG TIME . I've had some for at least 2-3 years that are on almost all day everyday and still function as they should. They can bend and be shape where you want them and will stay put. But beware. As with any thin wire, the more you stress one area or pinch it between something like a metal bedframe and wall it can sever it, but that's only happened once on one strand. I use them in my fall artificial maple tree, and then remove them and add to my bedroom Christmas tree. I've used some for inside my tent with camping too. And even put the color changing ones that use battery packs on our strollers for theme parks or in our bikes for night rides. They are excellent for most applications you could think to use them for. Great deal. This set is 2 Long strands. This is 3rd set I've purchased of these specific ones including gifting a set to my sister who loves them too.
