I can't believe I have had this glass tumbler for over 6 years! You can read the review I wrote 6 years ago here. It is over 6 years old but going strong!
The glass actually is flawless, but I accidentally smudged some sunscreen on it before I took this picture... (oops).
Some features I like: easy to clean, no lingering odour, durable, small holes make it impossible for tea leaves and coffee grinds to fall out of the strainer, every nook and cranny can be taken apart and cleaned, and you can add fruits and herbs in the strainer!
