Review title is Quit working after 12 days [SEP] Worked for 12 days, but on the 12th day, when it ran out of water and I pushed to button to turn it off, it would not turn off.  The Mode button also had ceased to work.  After about a minute of me pushing buttons and shaking it, if quit and indicated the battery was exhausted.  So much for going 30 days as advertised.  I recharged it for about 6 hours until it glowed green indicating a full charge, and I disconnected the cord for charging and pressed the on button but nothing and it immediately indicated it needed to be recharged.<br /><br />When it worked, I was not thrilled with it.  It has three buttons in a row at the top, the top one being the one to release the little nozzle wand for want of a better term, the second one the on/off button and the third being the mode button.  When you go  to use it, and you decide to stop while it still has water in it, you need to turn it off while keeping the nozzle wand in your mouth so you don't shoot water everywhere but you cannot see the buttons so you just start pushing and maybe you will get lucky and hit the power button, but just as often, you will hit the mode button and it just starts working at a different pressure as you grope around.  My solution was to not stop when I wanted to but keep going until it ran out, then pull it away from my face far enough to  find the buttons and turn it off.<br /><br />It is not practical to try to rotate the nozzle wand so is easier to use by just rotating the whole unit which means you lose track of where the buttons even are.
