Great thermos. Unfortunately I broke mine recently. Really my own fault. Dropped the darn thing on a tile floor. Bought a silly replacement and I now appreciate how great the mandala one was. With my new one I get a lot of tea buildup around the ‘strainer’ (not sure if that’s the real name for it) as it’s slanted inwards. Never had this issue with my mandala thermos. I had a few colleagues at work that enjoyed tea or I turned onto tea and they were constantly asking to borrow it simply as a brewing vessel. Great quality, just don’t drop it like I did! Price was high from mandala, but I’d rather pay that again than be stuck with the one I have now!
