I beg to differ, in fact I'd say that that skimmer deserves a spot in the Skimmer Hall of Fame. It was inexpensive, easy to dial in, easy to clean and repair, had a nice chamber for a heater and some chemical media, and you could just hang it right on your tank. CPR helped a lot of people have successful reef tanks back in the Nineties and really propelled the nano hobby with the Bak Pak.
Now the Skilter, that was a piece of junk.
I think it was a waste too... Aqua C Remora was way better.
