The design needs some work.
The filter is so deep into the cup that you can't fill more than half the cup with water, otherwise tea flakes spill over the edge of the filter. The other aspect is that the filter is so right-angled, anyone with wrist or hand difficulties (me) can't angle the cup to drink without hurting themselves.

I'd suggest the filter be closer to the lip of the mug, and able to rotate in an inset ring, masking it drinkable from any angle.

This tea mug is revolutionary! It makes the perfect gift for any occasion, and it's easy to use. Plus, it supports Nepalese women and small-business folks, so it's a SUPER ethical purchase. Highest recommendations. Namaste

Very easy to use

This is a brilliant, truly innovative design for a tea infuser. I always look for glass infusers because I never want other types of materials potentially interacting with tea. But the glass ones always break and it is cumbersome to keep track of 3 different pieces of the infuser. I also appreciate how the holes on this infuser are a little smaller than the ones on my last one. This infuser is simple, sturdy, and delivers a perfect cup of tea. I'm so happy to have found this product and will purchase again for gifts. Thank you!

The nice glass is wonderful for enjoying tea. No worry about the loose leaf tea. I do wish the galas cup was a little thicker but overall it is a great invention.
