My daughter used a previous generation of a fisher price training potty that actually had water in the "tank," where this one has LEDs. The water ended up eventually drying out and making the tank look ugly. I think that this version is a definite improvement.
The Fisher Price potty seat has also been a big hit as it plays a song every time he goes potty, he loves that actual musical reward after going potty. He is also a big fan of stickers and the chart to track progress has been a great visual help for both of us.
