This is the best invention ever made.It's too bad i couldn't use it til it was gone. My 7 year old & 2 year old was allerigic to it.But it sure did make doing the laundry alot easier while it lasted a whole 4 days and bout 10 loads later. If they wasn't allergic to it i'd buy it all the time.Great Great product.I would definatly recommed and did recommend it to my mom & dad.It was priced right and was simple to install and would be easy to change out when you needed to.The smell was great and you could smell it on your clothes up til 2 hours later
