I only got my Libré Tea infuser mug a little over a week ago and no word of a lie, I’ve probably used it over 50 times. I love the clever idea and how it is very calming watching the loose tea leaves float around my glass. I haven’t had any problems with tea coming through the strainer and it hasn’t leaked at all for me. I keeps your tea quite warm as well. My only complaints is that when you turn it upside down, then put it right side up again, and the open it, there is still a large amount of liquid that stays above the strainer and takes a minute to strain back down. This isn’t anyone’s fault, but just a tip to everyone to give it a second so that you don’t spill on yourself. The other thing is that the little gold emblem on the lid, tends to move around under the plastic top. This doesn’t normally bother me but sometimes it gets really off-centre. Lastly, and this one is my fault, the outside has gotten quite a few little scratches because I usually carry the mug around in my purse. They are not overly noticeable, but if you want your glass staying in pristine condition, I suggest not tossing it in your bag.
All in all, great product. I recommend it to every person who drinks tea, coffee, hot chocolate, etc. When I’m finished with my tea, I rinse it out and use it as my water bottle for the day. And I don’t even taste the tea in my water.
