I use this stainless steel strainer for brewing rooibos, and the holes are small enough that it keeps almost all of the little rooibos twigs inside. The holes in the glass strainer made by Trendglas let more of the rooibos through. This strainer is very convenient. It fits in the Trendglas Zyclo mug that I have, but also fits nicely in a beaker mug that was made by a different company. It is sturdy and well made, and smooth to touch. The one downside is that it gets hot because it is metal, so I have to wear gloves to pick it up while it is hot, whereas the glass strainer I can often handle with my bare hands. But the small hole size more than makes up for it, in my opinion.
