I wondered if I was being a bit extravagant as it’s not cheap. However, I love this glass infuser and it’s good quality. It feels like a bit of a luxurious treat every time I use it. It’s easy to use and to clean with a well thought out design. Mine hasn’t stained or discoloured. I put the glass mug in the dishwasher, add the used tea to the compost and just rinse the infuser under the tap. I think any herbal tea drinker would be pleased to receive one as a gift.
