Overall, the watch is cute. I initially bought it for my potty training daughter, but like me, she is VERY stubborn and nothing seems to work. She wanted a watch like her big sisters each have, so I got her a potty training watch. The time intervals are kind of weird to set up at first, but once you get the hang of it its pretty easy. It fit my daughter, however I had to put it on the smallest setting for her, and she will be turning 4 next month.Overall I’m pleased with this potty watch. It must be charged with the included cord (no wall plug included) and the battery lasts a day or two. This watch tells the time by lighting up two numbers at a time, there are no hands and it’s also not a digital number display. It’s been fine when my toddler washes her hands but I haven’t tested the water resistance past that. We also have the Potty Fun potty watch and I prefer that one because it doesn’t need charged, the band is quicker to put on, there’s almost no setup, and it’s cheaper. However that one doesn’t tell time and is definitely not water resistant. I’ve yet to find a perfect potty watch, but this one is great if you want one that tells the time and is water resistant too. Potty watches are nice because the watch is like a third party telling your child it’s time to use the restroom, instead of you telling them all the time and them resisting. So overall I recommend if you don’t mind charging it every couple days.I hope you found this review helpful ?We've just moved and are potty training--too much fun! We have a little girl and this was both a fun "I'm a big kid" thing and a reminder that it was time to try again. I'm not actually sure how much it helps since she was close to being there but she enjoyed having it and the other kids were excited to see it working. That being said, it was hard to set up (better instructions please) and it didn't seem to shut down so I was always trying to take it and charge it which was not a good time.It's a nice little watch device but it sounds kind of cheap.When you set it up, it gives you different time options. And it works.But don't expect much from the music. It sounds like something you would get from a vending machine. Pretty cheap in that area.It takes only a few minutes to charge. I don't know how long the charge lasts though.The band is soft rubber, so it should be comfortable for a child's arm, but probably not for an adult.This helps with toddlers who have a case of the me do it's! No parents to tell you when to go potty just an awesome watch that can light up, play songs, or vibrate!! Timer can be set at the 15, 30, 45 and 90 min marks. A bit large for toddler and she doesn't always like to wear it. Comes with a charging cable but no battery to charge must purchase separately or use one you already have.My son likes wearing it but I don’t know how to set it for the times I want. It just goes off on its own. Also battery don’t last long.
