I bought these for their convience and ease of storage. They are simple to use. Just throw in one fling...that's it! No mess, no measureing, no heavy jugs of detergent. These did a good job at cleaning my clothes. The only thing I was disappointed in was the lack of scent. On cold sniff, I love the fresh, sweet scent. However, there is absolutely no scent on the clothes. So what's the point of having scent, if its not there.
