"Exactly what I was looking for, and more"
I was looking for a stainless steel tumbler with a leak proof lid. This one even came with a tea strainer attachment/inner lid which is a big plus for me! Rather than putting loose tea into the strainer and discarding the tea leaves once brewed, I put the loose tea leaves on the bottom of the cup, attach the strainer lid, pour hot water, place the leak proof lid and out I go. I keep adding hot water to brew the tea more than once -- especially if it's a good quality green tea, you can definitely brew it more than once. It is absolutely leak proof so that I can just throw it in a bag and I don't have to worry about it leaking. I bought one for myself, one for my son and two to give as birthday presents to tea loving friends. They are all loving it. A great product.

"Outstanding"
I decided to become a tea drinker so I purchased this mug. I have to say that I think it is outstanding. It keeps your drink very hot for a long period of time. I filled my mug with tea, went to the gym, and an hour and a half later it was still almost too hot to drink (that was with the lid on of course). It still stays at a good temperature for drinking for several hours with the sipper lid on. But don't expect the mug to keep your hands warm on a cold day because even with almost boiling water in it it will be cool to the touch. I will say as other reviewers have noted that little bits of tea get through the mesh, but it doesn't bother me. I figure I'm just getting more leafy goodness! It is a bit expensive, but often times you only get what you pay for and I believe this item to be worth every penny. I have not tried any cold drinks, but I am sure it will perform just as well. It does make a small cup I'd say it only fits about 10 oz really. Overall great item, I am very pleased. [...]

"best coffee thermos i've found in 4 years"
i love this thermos so much, it goes everywhere with me. i've been searching for the perfect coffee/tea thermos forever, and i finally found it! keep hot stuff hot for over 6 hours, it's easy to clean, and it has a screw on lid so i can throw it in my backpack! it doesn't have any weird taste/smell - and it has a "wide mouth" so even soups or other hot food items could be stored in it. the tea infuser guy has relatively big holes in it, so if you're trying to brew a tea that has lots of little bits, it goes through it. but for tea leaves it's great. i bought one of these for my best friend hannah for her birthday a few months ago, and she still tells me DAILY, "i am in LOVE with this thing." (she usually screams the word love)

"great for tea lovers"
This has been a great product. I've used both the sipping lid and the tea infuser. Both have worked great. The lid is great when you simply want to throw the tumbler in a bag. The longest I've ever kept things in the tumbler is about 10 hours and it has been able to keep my teas warm for that long. Stylish and functional. I will warn those who want to use the infuser that you will need something to throw the tea leaves away in after you have brewed. However the tea infuser does clean up well.

"A+ thermos, best solution for tea on the go"
I bought this to replace a thermos I got for free and it solved virtually all my problems. It doesn't spill due to the gasket-ed lid, it's small enough to fit in most of my bags, and it has a tea strainer. Its size also makes it ideal to use at coffee shops instead of paper cups. The two small downsides are that no handle means I can't clip it to anything, and that the mesh of the tea basket is too wide for finer teas and yerba mate, but it still works. A plus, it kept my coffee warm while walking across town in below zero temps.
