The button on the side that is used to set the timer is really enticing for a three year old. Especially when it makes beeping noises and chimes when you push it over and over. He never got to experience the timer going off because he kept resetting the timer and playing with the button. The watch never got the chance to be used as a potty reminder. Poor design having the button to set everything accessible to the kid.My 2 year old daughter really liked the watch but I was never able to get it programmed.Doesn't work well, set it and doesn't go off. Haven't used because of the troublesThis is a cute little watch for kids to help with potty training.It’s got a cute little design. My daughter is three and would like this a lot. It’s a good way for them to feel grown up and special.Only 24 hour time. Broke after first 12 hours of use. Freaks out and and can't change or set time. Then when it finally allows you to set the time correctly, the timer goes off literally every five minutes. after the second recharge, had to completely reset clock time and timer.We worked for hours trying to get the watch to work for my husband and never got it to work.It was refurbished and so it would not connect with our phones.Loved it for the first two days or so. Now it turns itself off even if it's completely charged and will stop working. Would also recommend a way to lock the controls to keep your kid from changing the settings. Would be a great idea if it actually workedThis is not a good watch for toddlers.It was too easy for my son to mess with it and turn it off. We had it 1 day and returned it.
