In my opinion the design can use some improvements; either remove the handle so it sinks all the way in the cup, or better: add another handle so it can rest properly on the cup's edge.

Id say this would work perfect for anyone who doesn't have intentions of making a pot of tea and only prefers one cup at a time

Great design - fits both tall, narrow cups and shorter mugs.

I use this directly into my tea cup for a fresh cup of perfectly brewed tea, the holes are very small and I haven't had any sludge left over in my drink.

The leaves are very fine and this strainer did a wonderful job in providing me a nice chunk-and-leaf-free cup of yummy tea

It does not sit in wide mouth deep cups very well

I drink 2-4 cups of tea a day and I prefer loose leaf tea

The strainer works great as intended if you have the proper size cup.

and I have the perfect cup of Chai tea
