I like this a lot for brewing a single cup and then reusing the leaves. It’s a little annoying to clean, but so is my other plastic-cloth-style infuser. I thought it would last forever, but after only a handful of uses, there is a cut in the basket. I’m not sure what happened, or if it came that way and I didn’t notice it, but if you get one, assume that it is more fragile than it appears. I might have messed it up in the drying rack or something, I don’t know.
As for the quality of the steep- it does leave dusty particles in the tea, the perforations are tiny and fine, but some bits of tea will be tinier and finer. It doesn’t bother me, I can just play Professor Trelawney with the dust. But if you’re someone who needs crystal clear tea, this infuser won’t make it.
Late edit: After using this for a long time now, I have to amend my earlier assertion that this is a ‘little’ annoying to clean. This thing is really, really annoying to clean. Fragments of tea leaves get stuck in the perforations and you have to really work at it to get them out. The mesh style infusers are vastly easier to clean.
