We are trying to potty train in our house. When we first started potty training our daughter she would naturally slam the lid and the loud noise would scare her. So, from this point on she would not want to close it. The Shandle is a very inexpensive, easy to install helpful tool. The fun peek a boo theme from the top and full view when lid is up makes this fun for our daughter. Thus eliminating her fear of closing the lid. There is no more slamming with the Shandel and most important less smashed fingers. She seems to enjoy using it. Its almost like its a game for her now.
