I had a Brita water dispenser for a very long time. Someone gave me a barely-used Zero water dispenser, so I tried it. I didn't like it for a variety of reasons, and it broke within no time at all anyway. I ditched the Zero water dispenser and bought a new Brita dispenser. Easy and delicious!
I contacted Brita to tell them my story and to thank them for a great product. They were very kind, grateful for the positive feedback, and are sending me 2 credit coupons for my time and effort in writing to them.
They're great!
P.S. Their filters don't last as long as they used to, so I've gone to purchasing copies. They work just as well.
