I recently purchased this potty to start introducing the idea of potty training to my 18 month old twin girls. It is very easy to put together and only requires 3AA batteries. I decided to not turn on the sound for them yet as we aren't actively going to start potty training until we finish our move overseas this month. Even without the sound, this potty it wonderful! It is super easy to sit on and I like that it doesn't have a protruding splash guard that could possible injure little bottoms. My girls love that it flushes like a big potty and the sticker reel is awesome! This potty came with two sticker charts for tracking progress which is awesome since we would need one for each girl. This potty is a little smaller than the baby bjorn one, but my girls are in the 99th percentile and it is still big enough for them and compact enough to fit in our small bathroom. I tested the sensor and just one drop of water set off the "good job" song which is great! The songs are a little annoying, but it's for kids enjoyment, not mine! Overall, I love this purchase and will be ordering another one for the front bathroom in less than a month!
