"leak"
I really want to love this tea press but I can't get it to stop leaking when I pour it.

"Not Ideal"
I've had my Assam for 4+ years and use it every day. It's cute, sturdy, and--if you discard your tea after one infusion--very effective. Problems occur, however, for those like me who don't.
I buy expensive loose tea; one of my rationalizations is that such teas are good for at least three infusions. Once the Assam's plunger is depressed, it will indeed stop the brewing process...for the water in the pot proper. Unfortunately, it doesn't press out ALL of the water in the infuser basket, which contains what is, in effect, a small amount of very concentrated tea that continues to brew. In order to arrest this process, it's necessary to quickly (my tea is always timed precisely) remove basket, pry off the lid/plunger (which has formed a vacuum after being depressed), dribble this tea through the holes of the basket's sides into another container before it gets bitter and ruins the leaves for subsequent infusions, then add it to the tea in the pot (which otherwise isn't the strength it should be). It's a messy, tedious process that can result in burns and is a real pain in the posterior. In addition, tiny particles can escape the rather large holes in the basket (also problematic for many tisanes); unless these are strained, they continue to infuse, resulting in a bitter liquor. Unfortunately, this can cool the tea more than one would like. Over time, the pot and infuser become stained, the pouring spout isn't as good as it should be (but isn't as bad, in my experience, as others have described), and the basket doesn't stay put very well--a problem with hot beverages.
I appreciate the virtues of borosilicate glass and so was glad to learn that Bodum's recent De Chine line looks to be an improvement on the Assam and which--unlike its predecessor--is actually offered for sale by at least one online purveyor of fine tea. The pots are all glass with a large glass infuser/filter (which allows for observing "the agony of the leaves" and other brewing phenomena that make fine tea a delight to the eye as well as the nose and palate) and no plunger--one just removes the filter (which looks to have small enough holes to be practical; I hope there are enough of them). I hit Zabar's in the interest of further research and liked what I saw, although even if I purchase, I plan to eventually acquire several Yi Xing pots to dedicate specifically to the various greenish, flowery oolongs that I cherish; I'll continue to use glass for whites, greens, yellows, and blacks.
I'd probably rate this lower but for the fact that it really is cute and durable, plus I manage to brew great tea despite its performance flaws (although this is likely the result of my extreme scrupulousness with regard to water temperature and brewing time). My advice, if you're really serious about tea and want an all-around brewing device for more than one cup at a time, is to investigate the De Chine.

"it brews tea... wow?"
It steeps tea, plain and simple. Make sure you have a kettle, or something else to boil the water in as well. If you use loose tea, it brews just fine (if you only make 1 cup, you'll have to work the plunger a little to circulate the water, as 10oz is about the minimum for proper operation). If your tea is finely ground, it will go through the holes, but after it settles to the bottom theres not much to bother about.

The only thing I don't like about this, is that it stains very quickly. Considering that it is clear, it can be a bit ugly (when there is no tea in it).

"Great design, poor execution"
I have enjoyed my tea press, but there are a couple of things about it that do bother me. The first is that the lid/plunger assembly does not really fit squarely in the tea press. It's kind of loose on top, and I can't push it down to make it fit without risking a burn. If I do push it down on one side, it pops up on the opposite side. The second thing is that the plunger automatically goes down when the lid is on. I end up pulling it up over and over until I am ready for the tea to stop brewing. There's not enough friction in the design. I think better manufacturing would solve both of these problems.

"dripping teapot"
We had the teapot previously, but the top cracked. We replaced it with the new model which has a poorly designed spout/lip (narrow and pointed)and the new basket seals too tightly. This teapot drips when pouring and leaves a pool of tea on the table. If we want to reduce the dripping, we have to pour very s-l-o-w-l-y, which is frustrating. I even emailed Bodum to ask if they had the old basket to see if that may lessen the dripping. But I never received a response. Bad teapot!
