Well, I've been using it for a while now, and I'm not as impressed as I thought I'd be. The disadvantages are...
- Hard to empty. With my over-the-cup strainer, when I'm done brewing all I have to do is bang it against something to dislodge the old, wet tea leaves. Something made of glass has to be handled a little more gently.
- (I guess that was my main gripe.)
On the other hand, the advantages include...
- Self contained. The lid can even be used to place the filter on after brewing is finished.
- Looks. This nice-looking, well-designed item will definitely attract attention in your office.
- Practicality. When removing the filter from the cup, the tea drains through more quickly than you'd think, so you don't have to stand there holding a slow-dripping filter, as I worried might be the case.
To summarize: If you don't mind rinsing out the filter in a sink after each cup of tea you brew, this is a practical, visually appealing teacup-with-filter that's great for the home or office.
