Constantly drips

We bought two units, about 18months ago, we had to return one immediately because would not stop dripping all day long. Then my mothers started dripping last week. We checked the on-line FAQ about turning the temp down etc. The only way to stop the dripping is to go out and buy another dispenser for $150. The other one that was replaced is still working fine. But I really wouldn't recommend purchasing this product.
