I LOVE LOVE LOVE THIS PRODUCT!

I take it everywhere with me, it is small enough for my kiddo to pooty in the car or to bag it up and throw it in the stroller or diaper bag and then I just set it up on the restroom floor so I dont have to worry about big pottys . .. also once you go through the first set of refills, I just use grocery or produce bags! I cant say enough how much I love this thing!
good luck!
