I received these as part of a tea pack from David's Tea. After using them up I have come to the conclusion that they are not a good fit for my lifestyle and are a bit of a gimmick. The bags are much bigger than needed and the top of the sachet doesn't fully close allowing some of the smaller tea leaves to seep out. When you can just as easily (if not more easily) fill a reusable strainer, these throw away bags seem like unnecessary waste! I just can't see the point of buying loose leaf tea if you're going to buy throw away bags, anyways? I also find that my tea takes much longer to steep because the material isn't as permeable.

The only real use I see for these is if you're on the go and don't have a place to keep a reusable strainer before you can rinse it.
