Literally took me 10 minutes to fit, not bad for my first ever plumbing job. Water tastes way better even my 10 year old son noticed a difference.

Great Product, installation was simple and straightforward, and the difference in water taste is noticeable - much fresher and cleaner. Really pleased and would definitely recommend.
