Review on Bamboo Tumbler with Tea Infuser Bottle Loose Leaf Strainer: Advanced Double Insulated Stainless Steel Travel Thermos for Tea Lovers & Coffee Enthusiasts | Leak-Proof 17 oz Hot Coffee Mug & Fruit Water Bottle + by Stacy Sanders

I drink tea every day and take a glass with me everywhere. I absolutely love my new Nifty Core teacup! The jar is airtight, I know many jars claim to be, but this jar really is. I can turn it upside down and it won't leak! I didn't drop the glass but it seems solid. It is stainless steel wrapped with bamboo. Also, the lid is stainless steel, which is great since I don't use any products that contain BPA. It keeps the tea hot for a very long time. I fell asleep with the brewer in the glass, when I woke up the next morning the tea was still warm. I will order another one for my wife, she doesn't drink tea - crazy I know - but she does drink coffee. Speaking of coffee, the infuser is thin enough to brew coffee in a glass when you're short on time or on a hike. I was worried the glass would be sweet and slippery, this hasn't happened and it doesn't get hot when I add boiling water. It's not very slippery if you wash it in the sink as I used to break two glass jars - yes they were unbreakable. I think that's a minus, but I wouldn't wash it in the dishwasher, I'd be afraid it would ruin the look of the bamboo, and I get compliments on the glass at office meetings with clients. For me the size of the glass is perfect and allows me to hold 16 ounces of tea. I don't care for small 10oz or 12oz teacups, they just don't have enough liquid when I'm running errands during the day. All in all, I think I've finally found the perfect glass.
