as suggested by its name, the power hour is one where you put all your distractions aside and only focus on the important job. this whirlpool dishwasher was much better than i expected. "i learned that i could really make a difference in the world." i only leave them out 3 minutes at a time because it is so loud. i tend to keep this to once a month use, or when my skin is feeling particularly congested! don't get wall art because some artist or friend told you it is really great. thank you for all the work.
