Don't get it. I have to press power and then cycle through to get to the option I want. I then have to power it down and start all over again. I need a third button. I want to power it up, choose the option and then start/stop at will - keeping the option I chose. As it is I spew water everywhere while picking the settings and trying not to gag while dribbling the water out the front of my mouth all over my chin. becuase I can't stop and start at will. poorly designed and really hard to use because of this key use-case ! I want to return it asap as the mess in the bathroom and down my chin puts me off using it completely .
