I have read the reviews by people with boys potty training. Not sure why they are having trouble. Seat is simple no bells, voices or scary parts. Wide base for ease of getting on and off, the pee guard does not interfere with my two year old grandson and he gets on and off unaided. The trick to not having a boy pee between any area is to have them lean or sit forward so the aim is downward. Haven't tried the removable seat on the big toilet but I don't expect to need to. My kids went from the potty toilet to big toilet without the in-between step so won't be an issue for me.
Liked the larger bowl area not thrilled about the cushioned seat but seemed to be a feature on a lot of potty chairs. Looked at the bjorn but the bowl for disposal was too small could see number 2 being awkward to clean up. Also very clumsy to get on and off unaided, granted it would not tip but hand landing in the potty bowl was foreseeable.
Like the toilet roll being near at hand and that...
