I love the infuser bottle. It is my fav of all the accessories. But the 1st two times time I used it leaked and sprayed hot water all over me when I turned it over to infuse. Not fun! Then I realized I shouldn't fill it all the way. Mind you, I didn't fill it to the brim. I filled it up to just before you screw in the top. Now, I make sure to only fill 3/4 full and all is good. No more issues. A max fill line would've really benefitted that initial experience. I use it everyday now and am waiting for restock to buy another.
Love the bottle I carry it around with my tea in it at work hot or cold , love it ❤️
