Received this as a gift and use it pretty much every day. I like that it's glass so I don't get a metallic or plastic taste with my tea. Diffuser is easy to use - I put it in at night with hot water and let sit, then take to work the next day after adding ice for a nice herbal iced tea. Took off one start because it doesn't hold as much liquid as I'd like, only drawback to it.
