Love it x 3

I love this tea infuser so much, that I’m on my third one. The other two broke... and I went the distance to replace them.

Super Gorgeous

This is really a beautiful infuser. It's like a piece of art, actually. I cracked the first one and the customer service to replace it was exceptional. Beautiful product, great company.

Beautiful product

I love the simple, elegant construction and the graphic. I am especially pleased that it is dishwasher safe, since the graphic is printed on the inner layer of glass. Unfortunately, it does say that it is made in China, which I am not happy about - I wish an eco-friendly company like this one (they use soy ink for the notebooks, come on) would do manufacturing within the US to cut down on pollution from shipping and such. Oh well. Still a beautiful, well made product, which is why I gave it five stars.

Great purchase!

I absolutely adore this. It brews a delicious cup of tea plus is beautiful. It is also easy to clean. I love making tea in it at work. It allows me to sip as I please throughout the day.

Love it!

This is such a nice infuser. It seems very sturdy and well made. I have a lot of loose leaf teas that can be a pain to put in other small diffusers, but this is a nice large basket. I just put my tea and water in at night and have a fresh one in the AM. And the art is really nice to boot!

Good quality

I bought this for my wife for her birthday. The infuser is high quality. The glass, metal, and wood are all well made. The constellation art is crisp and easy to read.

Perfect Gift for the Tea Sommelier!

My wife absolutely loves this very elegant infuser. While she may not really be a Tea Sommelier, she is a true Tea Connoisseur who is always looking for a "better infuser". The Cognitive Surplus Night Sky Tea Infuser has really been an ideal gift and has been used regularly since opening on Christmas morning. The stainless basket is a bit challenging to remove without popping off the wire handle, but we figured it out with a little twist, it pops out much easier.

perfect travel companion

Perfect size Nice, hot tea on the go Would recommend

I absolutely love it but...

I bought this for myself after my family stole all my other tea infusers. I loved it so much and took such good care of it but recently I was handwashing it and since the bottom is so thin I applied a bit to much pressure and it broke. I was really sad and I would love to buy this again if they make the bottoms a bit thicker. Just be careful with cleaning them. Overall the design is really beautiful and it made my friends jealous.


I can't rave about these guys enough. Somehow my address in etsy was my old one, so somehow probably my fault, and they shipped it there. I couldn't get it, so they sent me a free replacement! that one got broken in the mail so they sent me a THIRD one! Just because they're nice! and didn't kick up a fuss at all!!!! Not to mention I love this so much. I'm an herbalist so this way I can have my herbal loose teas allllllll the time. Its beautiful, art, functional, and the thing that holds the tea leaves is hands down the best tea infuser ever. I love it.
