I have the 5oz system, and I love it. I received this one for my birthday.
I like it a lot, but not quite as much as the 5oz one. I love the glass. The size is really nice. I like the filter, but I wish it had a little handle on it, like the 5oz size does. I also wish there was a little bit of a raised area in the tea hat/tray for the filter so it wasn’t sitting flat against the bottom. Otherwise, I really like it.
