I am now using this for the 3rd month and my drinking water tastes so much better. I also use it for my cooking and it makes such a difference to the build up of scale in the pans and the kettle - there is none!
The filter is easy enough to change and the jug is a good size, I bought XL. This means I don't need to keep filling it. The only drawback is that this size would not fit in the fridge door and would have to stand on a shelf but this is no problem for me as I prefer the water at room temperature.
The only reason I did not give a 5 star is because the lid is a very tight fit and if you push it down too far at the handle end the flap that you pour the water into stays partly open. Also the plastic has broken on the hinge at the small pouring flap but thankfully at the moment it still works. Overall I am still very happy with the results, I live in a hard water area, so I really notice the difference and and I will continue to use filtered water from now on.
