"Very useful when using loose tea"
I recently bought this new tea strainer. I was drawn to the built in plunger to squeeze the tea once brewed. It certainly does the trick. It is simple to use and washes easily. Made of plastic but not sure what the internal spring is made of. The size is good for a mug. The only drawback is that the strainer lid comes away easily from the main body of the strainer when opening it up. The lugs that hold the lid on are quite small. It's easy enough to push it back into place but the concern is that the lugs will wear after repeated replacements and the strainer will not be useable.
