Review Content Pretty Cool No more worries about resetting the clock when the power goes out....this gem is powered with water (actually H20). Setting the time was easy and with no cords or batteries to fool around with, its super easy to move around. Great for anyone and a fun gift. So complicated to use I gave it away could not figure out how to set the clock or the alarm....was so frustrated I got ready to send it back when friend said she would try to use it....have not heard back from her. Just wanted to get it out of my sight H2O Power Still havent figured out how to see it in the dark and shut off the alarm so havent used the alarm feature....yet This is my second purchase. LOVE IT Easy Directions! Does Exactly What it says it will do. Love it so much that I purchased a Second one. Love this clock, novel design! Gift for my niece whom is very concerned about the environment! techno style I like it for decoration to have the time with a techno and modern style.
