It's a fabulous filter system, the pool was sparkling again within a day or two. Very easy to install and to keep clean. Inside filter can be removed for cleaning. While leaving the larger outside filter in the container you can simply hose off in there and not have to worry about lifting it out. There is a very large drain plug that you can remove to let all the dirt and debris out. The clamp system is so much easier than having to deal with the ring system.
