Excellent - easy to fit and much better tasting water. Great customer service too!
I'm really pleased with it! After a few days for the tiny bubbles (which made the water look cloudly at first) the water is noticeably improved over our tap water supply and it's now my go-to source for drinking water. No more expensive bottled water, no more plastic waste!So good I bought a second one for our office.There was a small broken connector when it arrived but I'm still giving 5 stars as the customer service was excellent and they got me a replacement part very quickly

Simple and straight forward replacement.
In very simple terms these cartridges are an excellent choice. They were an absolutely perfect replacement for my existing set with full fitting included just in case you need it. Will buy again.
