This toilet (RMIT students call it a sprinkler) I have been using it for almost 2 years. Drops on the floor many times. The current situation is very good. My house has 4 people, each person uses 3 times per day, 12 times per day for more than 600 days. Overall okay.
Signing it as Justime, not knowing if it was still sold, from the nozzle body to the button were all metal so it was very durable and hard.
Spray feeling: very strong and clean. The first time you use this tap you need to spray it out first to know the pressure and practice the controls of the trigger. It is not too difficult, my child is small and can be used well.
