Know of no better and we've tried several

We have the pot in the combi blue with white insert and are thrilled. The emptying of the large and small businesses is working fine and the Conn. Cleaning is not as cumbersome as with a normal large pot (we had the least expensive version of IKEA and a pot of NUK compared).
Unfortunately, we purchased the potty at the 2nd child (at that time was too expensive us), we paid 26.99 euros for the pot on offer, still a lot of money, but the potty stops guaranteed another two children (would be great if there were individually at the use).
Advantages: The Po "sticks" not on the pot, the easy cleaning, the seat and catch size of the insert is of sufficient size to safely usable for boys (the NUK potty was for our boys a disaster), practically the high backrest is otherwise good stability, appealing design.
The only downside (which is why a point deduction) is the high purchase price. Therefore my tip: leave pay !!
