Unfortunately I did not read the reviews before buying this mobile here ... a bad mistake. To make a long story short - I can give the already created here 1-star reviewers just right: - Installation - hardly cope (and that's where I'm technically not untalented) - Quality - miserable - cheaper to dismantle plastic scrap from China at great expense hardly anything to screw that are over after a few applications, plug-ins, the breakup, if you want to solve it - Mounting to a bed is actually impossible because the Mobile for cheap screw is too heavy a lot, and then diagonally hanging in bed and bobbing and holds really not good - The music - well, were it not for the strange whirring noise of the "transmission" of plastic gears and the cheap sound - Lighting up - nice thought, poorly made ... just like on the packaging, it does not look, is very weak, can be seen only in a black room a bit on the ceiling, and then but not much ... - The lighting down - catastrophic - bad - just made - our child got scared ... looks like a hypnosis spiral - The price - for that gets what you offer here would be even 20 euros too much ... - Battery replacement is only possible in the 6 screws are loosened ... this was ever to assemble only been difficult disassembly probably scrapped the whole thing .... - The only positive: the look .. the whole thing is really cute ... just what good already ??? - Conclusion: we had only raise a Sterntaler-Mobile, thought something better to find herein, the Fisher-Price-Mobile will now break down again and stay with our good old Sterntaler ... that you have to raise it, but - it costs no batteries, the melody sounds nice, it turns, keeps it, there is no risk of injury to the child .... and it also like ... - NEVER AGAIN FISHER-PRICE -
