You get what you pay for. I'm happy with it, because it only cost me 40 dollars shipped. I'm using it on a 44 pent and my water quality has gone way up. Of course, the skimmer that I had before that was a berlin airlift. (no powerhead, just a cork air diffuser). I don't know much about the Bak Pak 2r, but if you dont have an incredible load on your tank this skimmer would probably suffice. It takes a lot of patience to get running, but when it does it produces plenty of nice "dry" foam.
