Review on Premium BPA-Free Double Wall Glass Tea Tumbler - Pure Zen Travel Mug with Stainless Steel Infuser - Leakproof Tea Bottle with Strainer for Loose Leaf Tea and Fruit Water - 13 Ounce Capacity by Angel Caldwell

A few days ago I received my Pure Zen teacup with infuser. The first thing I noticed was the packaging. It was in a hard cardboard tube and then Bubble Rap. Also, it has a neoprene sleeve for extra protection. Of course the packaging is great, but like a bottle. This bottle is well put together. It has a certain weight and feels high quality. I didn't leak at all. The same goes for the tea basket, it's well built. This part of the tumbler immediately convinced me. I've had many of these, but this one impressed me with how well it was put together. So I decided to brew two different teas in the same amount of time that I use in my old brew tea. As a big tea lover, I would rate the teapot as average. After pulling out the basket at the end of the time, I found the tea to be a little weaker than my old teapot. Probably letting it sit a little longer will solve this problem. Next, it's time to find out how well this thing keeps your tea warm. (didn't try it cold because I wouldn't use it to make cold drinks) So I tried it with and without the neoprene sleeve. The first thing I noticed in both tests was that the glass was already heating up from the outside. Keeping warm or cold a little longer is a bad sign. I'd say sleeveless luck warming up in an hour. With a sleeve it took about 2 hours. As a glass to make and drink tea I would say this is a great product. I would say that making tea and wanting it to be warm after about an hour is not a big deal. Impressed overall, but the star had to be removed as it was losing heat so quickly. If I run into leak issues (which I didn't) I'll come back and update.
