Looks great, doesn't it? Great filtration.. Then you have the faucet. A piece that does all the work manipulating the water on and off. Sounds easy.... and it is. Except when they cheap out and make the stem that holds the faucest to the sink out of plastic. It will snap off with just finger tightening at its weakest point. That is what happened to mine. I had to buy one from a home center (with a brass stem) and finish the installation. Too bad, really. It could be great...
