I've been using this filter for yeaaaaars and it's worked great. Maybe your friend lives somewhere where his/her water is very polluted with metals ect. But where I live it works just fine, your friend may have also used it wrong, you have to keep a correct water flow through it, that means, not to fast not to slow or it will screw up the whole proccess. I admit, theres no doubt that RO/DI units are much much better than this simple tap water purifier, but for someone who isn't looking to spend a lot of money it's very affordable and the results are very good. And beleive me, I'm no novice, I've kept and still keep many "expert only" fish and inverts. Some that I have now just to name a few: Seahorses, Octopus, Freshwater Stingray, Discus, Flame Scallops, and a variety of nudibranches, and I havn't lost any of them yet! So I think this device is sufficient enough. :yes:
