Review (4/5): A bit hard to open
I like this unit because it doesn't take up a lot of space to store. It fits nicely in my medicine cabinet. I do find it quite difficult to open to fill or drain. Maybe it's just the one I got, but it's stiff and hard to crack it open. Because of the design, it's hard to get a good grip to twist it without hitting the power button and squirting water everywhere. But it does a good job for the price.
