Really love how cute and convenient the mug is for brewing loose teas! I bought one for my mom and myself during the Christmas sale. Mine developed a 2 inch long hairline crack from the top of the mug extending into the mug after I used it one time! I didn't drop it or hit it against anything either. I will be buying another one just in case this crack gets worse because I think the mug design has huge potential to be great.
I originally came across this product on Amazon and ordered but it kept arriving broken so I went straight to the source to buy a new one. It arrived perfectly and I love it. I use it everyday, it's great for keeping my drink warm, it's getting plenty of use this winter. Liked the first one so much I bought another as a gift.
