This little teapot holds enough for a couple of decent-sized mugs of tea. It's perfect for two, or one tea-addict, heh. The diffuser basket isn't the most stellar workmanship I've ever experienced in my life, but it'll do. The basket is perfectly suitable for black, green, or any sort of herbal, but with rooibos I've found it sneaks through the cracks a bit. Not enough to be that big of a deal, but it can be a bit annoying.Now, the teapot is glass with a plastic handle/bottom/lid. If you're keen on washing it after every use, you'll find that water can get stuck in between the glass and the plastic, and slowly leak out later. Personally, I don't fully submerge my pot with soap and water every use, so it's not a problem for me, as a quick rinse is fine. But keep this in mind if that's something you do.The real winner for me with this pot is that it keeps my tea warm for a surprisingly long time (with the lid on). I'm not sure if this is average, but for a small and light pot, my tea was still warm after 75+ minutes. It's quite nice to drink a cup and when I pour another it's still pleasantly warm. Also: no leaks. Keep the lid on when you pour, and keep light pressure on it while tilting, but otherwise, it's a great little pot for the price.
