I read the other reviews but figured I'd take my chances since my husband is pretty good at repairing these kinds of things. So we got the watch and it didn't work at all. My husband was able to repair it and then we figured out how to use it--you can choose between PLAY mode which lets your kid just listen to the song and watch the pretty lights; or you can choose 30, 60, or 90 minutes; or OFF. We set it for 30 minutes, put it on our kid and it was MAGIC!!! As soon as the song played he was on his feet and excited to go potty. This kid was so resistant to potty training he would pee on furniture, the floor, you name it--anything but the potty. And here he was racing off to pee without even a whine! Jackpot!! We got about a half day of perfect pottying BUT THEN the darn watch stopped working again. This time hubby couldn't save it. But this thing works SO GREAT when it actually works!! Please someone just improve the quality of this watch. We're going to try again with a second one and I'll update this review after we see how that one works. Maybe the first was just a dud? Fingers crossed because we need this to work!
**UPDATE**
This watch worked upon arrival and did okay for awhile. My son has never done this well with potty training before. We've been using our second potty watch for two days now and there have been NO accidents. The watch worked great for the first day, and the song was cute and really worked to remind him without us needing to nag him all the time. He likes having his own watch and the lights and music are pleasant reminders (mom and dad are annoying ones). HOWEVER, on the second day the music stopped playing for some reason. The lights still work, but they are harder to see and not as good a reminder as the sound. We've started using the timer on our phones again, and my son is becoming resistant to our reminders again. I'll update again if there is anything noteworthy to tell. Good luck.

The sound stopped working 3 days later smdh but it will light up when the timer end. But she still wear it

Received the Potty watch in the mail today... device doesn't work😩 I was so excited for my baby about this item, now I'm super bummed ☹ï¸

I received this watch in what looked like a none working state. Right before I was about to return it I looked at the manufacture website and they had a neat little trouble shooting video posted. I just had use something hard to press down the timer button. Try that first!!

So excited to get this and try it on my 2 old, opened the package and nothing. Absolutely nothing. Maybe the battery is dead, but the way the watch is designed its very hard to access the back panel. The strap is bolted to the back and you need a very small screw driver to unscrew the 2 screws. Im sending this back and will try one more time. Im im love with the concept of this, but if the product doesnt work ill be rather disappointed.
