Very dissapointed with my purchase.1. Even if you turn the volume to its lowest setting the keyboard sound is too loud. Worse, its default setting is 5 (scale from 1 to 10) which is way too loud. Each time your child turns the unit on and starts playing without thinking to turn down the volume first you have to hold your ears. Especially if you smaller children you know they are not going to turn down the volume by themselves.2. The various sounds are quite dissapointing. Of the 100 or so sounds I can only stand the piano sound which sounds ok - not great.3. The unit comes without a power supply so you better buy lots of batteries.I didn't expect much when I bought the unit. It was to be a simple toy for my 2 year old daughter. We will have to throw it out, primarily because of the volume issue.
