Potty Training Watch – Does It Work?

I am in the process of potty training my 2 year old daughter and let me tell you it is not as easy as my boys were. Is it true that boys are easier to potty train than girls or is it vice versa? Well upon hearing about my struggles, a friend of mine suggested a 'potty watch.' I had never heard of this, much less used one. 

It's a cute, little watch that plays music and flashes lights to remind your little one, in a fun way, when it's time to go potty! It claims to help shorten potty training, by reminding the littles that it's time to 'try to go potty.' Have you used one of these watches on your child and did it work? I think I'm to the point where I'm ready to try anything! lol
