Query: Ok...

The mobile is ok (at best). You definitely have to have the right crib for it to fit. We had to tie it on with matching fabric b/c it wouldn't fit around the rail. Also, the arm is white plastic. Hopefully you like the look of plastic put together looking like a puzzle...it's definitely not high quality...but if you're a big enough fan, you'll stick with it for fear of being a "fair weather fan"!!!!
