My daughter got one first, and I was very sceptical until I tasted her water. I drink about 2.5 litres of tap water a day. It has made a huge difference Her first filter she just changed convinced me to get one. Easy to install. A tad bulky for my little sink, but one feature I think is great is that I can flick it off to do dishes. Its worth the little inconvenience of manoeuvring around it. Worth every cent!
