Could wash on top rack in dishwasher, not bottom.
My friend really seemed to love the gift and she said that the constellations were great when she poured a hot drink in it.
This was the perfect gift for my daughter, who is an avid coffee lover & a Ph.D. candidate in astronomy/astrophysics. She likes its large capacity & fun factor.
my father in law is a huge astronomy fanatic and a coffee drinker, but already has most of the gear he would want. So this gift was the perfect surprise for his birthday. He enjoyed watching the constellations come to life.
My daughter loves this, great way to encourage interest in astronomy/constellations.
Easy to use and works well.

This mug was pretty cool. When it's cold it is speckled with stars, when you pour something hot in it like tea, all of the constellations pop up to connect the stars. I gave it to my astrology loving boyfriend as a gift and he thought it was sweet
It's really cool to watch the mug change once your pour coffee or tea into it!
Very cool mug! Bought this for my husband to take to work with him. Does exactly what it says. Only con is you have to wash by hand and it's not microwaveable safe.
The cup is great. The constellations appear with their names when the cup Is filled with hot liquid.
