Great tea diffuser, fragile

This tea diffuser has been great. I've wanted something so I can use loose-leaf tea and generate less waste, and this has worked really well. The one thing I'd say is that the glass breaks very easily. I probably could've been more careful with the first two I bought, but make sure to be very delicate with this.

Elegant and useful

I love the beautiful visual design on this infuser bottle, which tells me why my tea addiction is definitely a good thing. :) it’s lovely to drink out of glass; this bottle keeps it hot longer than a single layer, although not nearly as long as a metal insulated bottle. The infuser itself is perfect — tiny holes, contains whatever tea or other herbs I use without leaking crumbs, and has a thoughtful design that enables me to take it out of the hot tea without burning my fingers. The lid is just beautiful, too, and seals right. The diameter of the bottle fits perfectly into cupholders. I feel like I’m getting a luxury experience every time I use this bottle. It is well worth the splurge.

Husband loves this

My husband loves this and uses it constantly. It keeps his tea hot. He is walking up and down stairs so the lid keeps spills to a minimum. It does get hot to the touch on the outside after awhile but he can still handle it.

Love this tea infuser

I love the fact that you can look at the molecular structure of the tea and memorize the compounds within it. It's a very impressive and thought-provoking piece. I love flaunting it. ☺️

Tea Time

I love my tea holder with built in strainer. It travels to work with me and allows me to have fresh brewed tea anywhere because of the lid

may be susceptive to heat transfer

Glass travel mug with tea infuser: 1) there seems to be significant heat transfer from the inner vessel to the outer glass. I have owned several double-walled glass tea travel mugs like this. My favorite one was made and sold Teavana before it was sold to Starbucks. That glass vessel had little to no heat transfer to the outer wall, and it was never too hot to handle with the bare hand. Unfortunately, I have found that I need to place this vessel on coasters and have had to be careful when I handle it after pouring boiling water into it. As a result of the heat transfer, the liquid looses heat more quickly than advertised. 2) I ABSOLUTELY LOVE that the organic compounds are drawn on the inner wall of this double-walled glass tea container. 3) I really like the large capacity of the tea basket in the container.

Excellent quality, love it!

Got this as a holiday gift for my husband. Bought a fossil tea infuser before and both of them are amazing.

My first bottle was accidentally broken, I sent in pictures and I didn’t even have to request a replacement because they sent me a new bottle right away! Amazing customer service and awesome design! Thank you!
