What did you use to potty train your Son? I am considering the below trainer. Would u recommend it?

That is adorable! Oh my goodness I can't get over how cute they are hahaha. Usually my friends use the simple ones that you put over the adult toilet but I've seen one of my nieces use a musical princess potty. I've attached a picture below but it's not the exact piece, close enough though. A potty throne fit for a princess.
