Good toy, but quality needs to improve

My triplets enjoyed this Step'n Play Piano, however the piano keys on the bottom where they stepped cracked very easily. Perhaps those keys should be made out of something more durable. I do love how they can walk back and forth and the seat does a full 360 and there is toys on both sides. The batteries go very quickly though so it would be nice to have a wall adapter that we could plug in while not in use to "charge" it. Overall a good toy, but durability could be better
