I love this thing, I've grown up without ever using a water filter, always telling my self the city water is safe. But the wife and I are trying to be more healthy, I guess she wants to live longer.... So, hated the Brita, cause its either this massive baseball size filter on your faucet. Also the ones you fill the pitcher, then put it in the fridge, just a hassle. This took about 20 min to install, they provide all hardware, and fittings to make it fit almost any normal under sink water fitting. After about a week of using it, and boycotting my city water, I put 2 glasses of water on the counter and asked my wife to tell me if she can tell the difference, she didn't even need to taste it to tell the difference. As she put the glass up to her mouth to take a drink she immediately stoped and said that's city. She and I can just smell the copper metal smell in the city. We've been so immune to what our water taste like and smells like to go back would be unbelievable. So yes I recommend this, very affordable and easy to use, install and replace filters. which by the way are only $15 every 6 months to a year! BUY IT
