I had the old under the sink model for over 7 years and it worked great; but the new model improved the ease of changing the filters and the faucet no longer drips after it is turned off.
Pros: Clean taste, Durable, Easy to clean, Easy to install, Long lasting filter, No More Water Dripping
I love everything except the slow pour. I got a glass jug with a tap ( like you might use for lemonade) and I fill that and keep it on my counter. Seems to be a good solution. It was easy to install, doesn't take up much room under. The sink and so far we are happy with it. We haven't had to replace the filter yet though.
Pros: Clean taste, Easy to clean, Easy to install, Long lasting filter
Easy installation, good quality water. Easy access to change filters. The faucet that comes with it is good quality. Overall happy with product. The only drawback is that the water flow rate is somewhat slow. It takes a few seconds to fill a glass of water.
