Don't do what I did. When you take this out of the box and begin unpacking there will be two green straps that you will naturally mistake as some fastener holding the product in the box. It isn't. It's the straps that hold the device to the crib. After cutting one of mine I wound up needing to fabricate one of my own(PAIN!). What is it with the way stuff is packaged these days?? Do packaging engineers get off frustrating purchasers of their products who want to just simply open a box and use it??? O.K., rant off... I've only had this soother for a couple weeks, but so far I love it. The thing I like most is the colors; they're very rich and vivid. The music isn't bad(won't drive you nuts) and the movement of the animals is smooth. Battery life is O.K. so far(haven't needed replacement). All-in-all, short of the packaging, I would say this is a well assembled, well designed, quality item.
