So I have every size bodum, both in glass and polycarbonate. They are indispensible in my kitchen, getting daily use. I have to say this one is my least favorite.
positive: it's unbreakable.
negative: it's not as pretty as the chambord (cheap and plasticy), the plunger doesn't come apart, and the mesh in the plunger isn't replaceable. The size is really only workable for one.
While in theory the single piece plunger seems a positive, in practice it just doesn't work as efficiently as the three piece chambord's. The last few times I've used it, I've had an unpleasant faceful of coffee squirted at me because the seal is too tight and the nylon mesh gets deposits over time that occludes the holes. This makes it esssentially useless over time, since you can't replace the mesh. Even vinegar rinses don't help with this, since the deposits have an oily component from the bean.
As for the Chambord-- it's beautiful, breaks easily, but at least replacement carafes and mesh strainers are available for an overhaul after a year or two of use. Bonus: It will never scald you.
I also recommend not getting anything smaller than the 4-cup or 8-cup. Before getting the 4-cup, I constantly used to try to eak out 2 cups of tea out of this by filling to the very top. No good. you get a better plunge when there's room at the top, and less overflow potential as the grounds/leaves swell.
(BTW, I use these for tea and coffee interchangeably, and have found that the nylon mesh retains flavors unlike the metal strainer of the chambord.) Bottom line, I think the Chambord is the way to go.
