I received this complimentary from Brita Hub powered by Hamilton Beach and I love having really clean water for my Tea or Coffee. It is super easy to use. All I did was put in the filter it came with and added water and plugged it in. It has a 12-ounce setting, or 20 ounce and a manual dispense button. It has a add water light and filter life light. My kids love making Kool-Aid and this way it is easy and more convenient for them. I love it! The filter last 6 months.
