Query: Frustration

I would like to say how well this thing works, but you see the screws to the battery compartment are screwed in so tight it is impossible to open. We took the first one back to Toys R Us and they couldn't open it so they gave us a new one. Well guess what same problem. Last time I could get the remote opened, this time I can get one screw off the mobile. If it doesn't loosen by tomorrow, it's going back for good and I will choose something by another company.
