We bought this for our son when we moved in to a new house. He does love it and it calms him right back to sleep. Even after 6 months he still loves to watch the lights. It is let down by the music on sensor mode doesn't last long, just 5 songs lasting a couple of minutes in total. It is also very sensitive and I am glad i removed it from his cot, woke him up every time he moved. I'd recommed putting it outside the cot on a chair for example, somewhere where baby's movement won't trigger it to get the best result out of this. Otherwise great product
