I love this mug! The strainer is big enough to allow room for the tea leaves to expand. The mug design is simple and I love the lavender color and the texture of triangular shapes (helps with grip). Minus one star because the lid could be flat on top since you flip it over to rest the strainer on. It's rounded, which makes it wobble around on your surface.
I have used the infusion cup hundreds of times and I love it. It keeps the tea hot, but is not too hot to hold. The infusion basket does not drip or make a mess. After you infuse the tea leaves you can place the infusion cup on the cup lid. It is a very satisfying way to seep and drink tea. I have given these cups as gifts too. They make great gifts.
