The opening for water is very small and can be difficult to pour water into it without pouring it into the coffee bean area. Poorly designed, especially for people with arthritic hands.
This is the best coffee maker -- and white is the best color and glass is the best pot material. I have been buying this coffee maker (including it's predecessor models) for several years and will continue to do so as long as they don't change its features and design.
After my last carafe of more than 5 years unexpectedly broke, I bought this one. No issues. Glad I was able to buy the carafe and not a whole new coffee pot.
