I have the PoolSkim and it works for me. I do not have leaves in my pool but I get dust, bugs, grass clippings. The top of my water when viewed at an angle was always dirty. I have two skimmers but since I use a 2sp pump on low I never get enough suction or water movement.
Then I ordered the PoolSkim. Since I do not have leaves, I removed the blue net and attached a skimmer sock in its place. It filters all the small items that plague my pool. It is not perfect, I have to swap out the skimmer sock once a week and they last maybe two-three weeks. Also, I have 5 returns and in order to get enough pressure on low pump speed I had to put the PoolSkim on the first return coming from the pump and closed off the second return. One issue I have is that my PB used slip return eyes, meaning no threads so I had to modify my return with threaded couplings and had to use underwater putty to hold it in its place. Sometimes the threaded coupling comes undone and I have to putty it again. All in all, it is still worth the small hassles.
