100% recommended to anyone looking for a counter top filter. Does all we need.
Refilling is the only downside which isn't even that bad 5L tank which we refill twice a day at the very most.
Easy to use and does hot water for teas and coffee.
Very pleased with this machine
initial flushing process reassuring, as recommended I ran additional flushes and the result was very nice tasting water. The device is in constant use. Future improvements would be a larger screen to make it easier to see as one gets older and it would be nice for the display to also show the volume selected as well as the temperature. Perhaps an option to plumb it it in would also be a request. But, in summary, I wouldn't be without one of these machines.
So far great
Great!
