I have a glass tea pot that I have been using often for the past 6 months while brewing teas, especially greens. What I like about it is watching the leaves perform their dance while they are being brewed. It does have that coil spring strainer in it that is very easy to clean, you simply press on it from the inside of the pot and it unhooks from the spout.
I'm using that pot right now. This morning it's a jasmine pearl tea brewing on it's second infusion.
