Bests & Worsts Reviews from Amazon

I've used one of these for a few years now, and love/hate it. First, the idea is sound and it does make a great cup of coffee. But it is NOT durable. Don't even think about putting one in a dishwasher, or the plastic will craze and begin leaking. To the manufacturer's credit, they do tell you this if you read the documentation. And, if you store it upside-down - the seal unseats and will dry out. The result is a puddle next time until the seal moistens up and becomes tight again. The lid - if you get one - is concave and dishes inward. So if you're trying to max the capacity, you'll coat the inside of the lid with coffee mud. Even with it's faults, I love the coffee it makes and just keep replacing them. I'm wearing out number five right now. I'd LOVE to see this thing redesigned in glass or ceramic. And if the lid was redesigned to be convex - so the center clears the upper edge of the dripper by at least a quarter-inch - you'd have the perfect product IMO. UPDATE - 03/25/12 - Number five is worn out. It lasted about 9 months, used between once and twice a day. It's never been in a dishwasher or microwave yet it is thoroughly crazed and leaking. UPDATE - 11/13/15 - The one that I've gotten since the last update is holding up great, so the material it's currently made of is vastly improved. It now has a rounded base, that's really the only obvious visual cue that differentiates it from it's predecessor. But it's still plastic. However, I'm bumping the rating up to four stars because of the improvement.
