Great sound. Can connect to my laptop, my phone, or my iPad. Doesn't work without the remote control,though. Don't lose it or you're screwed. A light is constantly on. Red for off, blue for on. Have to cover it up at night as that red is pretty bright. My only real complaint is that it auto-turns itself off if you aren't listening to something for a few minutes, then takes about a minute to get itself sorted out after you turn it on again. Literally in the time it takes for me to nip upstairs and make a cup of tea, it's turned itself off. It's a minor annoyance. Otherwise this is awesome!
