Overall very smooth and easy. I love everything it filters and the amount of things it filters is the only reason I keep using it. However, getting there requires a lot of daily work. Since it is not connected to the water supply, you have to fill it manually. For me and my family we use at least 3 gallons a day (that's the max capacity) so I fill it up at least once a day. And so it's a few trips back and forth from the tank to the sink to fill it up. Honestly, I don't mind, like I said, I'll do it for Good Water. The only thing I fault is how the filter and what it holds, how it is arranged. They must be properly equipped with filters and a container, otherwise unfiltered water will go through and contaminate the already filtered water. One of the wing nuts is poorly designed and loosens severely, allowing water to seep through. I'll see if the company helps with this, I'll update my review based on what I find.
