Review on Potty Time Resistant Automatic Reminders Potty Training ... Potties & Seats by Heidi Ward

I bought the watch a year ago when we first started potty training at 18 months. My daughter was too young at the time to actually use the watch, but I recently stayed to use it again after another child caused it to regress. It was great, but the green watch I bought a year ago started to rust on the inside from washing her hands. It still works and she loves it so I bought a new one. The first came with a loose battery case and didn't work. Not sure why the second one didn't work as I didn't even bother opening the back. Now I'm trying other watches but I'm giving this one 3 stars because it has worked well for several months.
