I was interested to read the article in todays Herald Sun discussing the costs and negative feedback on the usability of these toilets.
By coincidence, just this weekend, I was at a playground in Narre Warren with my daughters when one wanted to go to the toilet. I took her over to the Exeloo.
The state of the toilet was disgusting. Everything was wet, especially the floors. I ended up taking my daughter out and had go behind a tree.
