This mobile is great! We've had it for about a month now and haven't had to replace the batteries yet. I use it almost every night, but pick and choose which feature to use. Some nights we only use the movement, sometimes we use the light projector on the ceiling, others we only use the light facing down. The only problem i have is that the cycle is only for about 10 minutes and that just doesn't seem long enough to help every time. 20 min would be much better. There is a remote control to operate it but you don't really need it because ANY remote control will operate it. If I'm adjusting the tv volume in my sons room while I'm rocking and feeding him in our glider it turns on the mobile...kinda funny, kinda annoying though. overall this was a great purchase, id do it again!
