I really liked this product. I'm not sure how well it would do with the kids summer laundry though. But I would be willing to buy again and try.
I have only used it once so far and it worked fine on a light load. I am going to keep it on hand for travelling. It is a very convenient product.
I purchased this size to try it out. I did several loads of laundry with it yesterday and I couldn't be happier. No mess no fuss, no pouring, measuring, etc - I can't believe how good it works!
