I bought this coffee maker to replace an old Ninja brewer that I'd had for about 5 years. It had always worked great, but the clock shorted out and being able to program that was important to me. I figured this was just the next generation of the same one. Unfortunately I may have received a unit with a defective water sensor. About 50% of the time it stops and tells me I need to add more water when there's plenty filled. Every time I've thought about reaching out for help, it starts working again flawlessly for a few days, so I'm not sure. When it works, it works great and it has all the functionality I've been looking for. I'm hopeful the water sensor issue resolves itself but time will tell if this machine lasts.
