Sea Turtle Heat Changing Coffee Mug - Color Changing Mug - Ceramic Coffee Mug for Men Women Black and White

Great size and love the design.

I gave this to my child for a birthday gift as he loves octopus. He loved that the octopus changed color once the hot beverage was poured in the mug. It was a great surprise! The colors are vibrant and the cup is nice and smooth with a well shaped, easy-to-grip handle. I highly recommend this mug!

I really like this, the shape, the way it fits in your hand, perfect weight AND beautiful!! coloring changing on the beautiful turtle is wonderful. Going to get the octopus next!

I got this for a Christmas gift exchange, so I have not tested or used the mug; bit I did open it up to look it over. The octopus print quality is great, and it's one of the only heat changing mugs that is dishwasher safe. I will say the handle feels a little questionable - it's very obvious that the handle is glued on. It's not a seemless connection, which makes me wonder how long it'll stay connected. Regardless, I think the present will be received well.

The media could not be loaded.  This was a huge hit for grandma on mother's day! It took just a few seconds to fully change from black into color and was cool to watch. Item arrived on time and well packaged. Will definitely be purchasing more in the future!

Got this for a gift and they loved it!

I gifted this mug to my Aunt for her birthday and she opened it and was immediately excited to receive the mug because it has a turtle on the mug. But the color changing effect does not work we tried hot water for 5 mins nothing happened. Is there a way to make that work? She said she still loved the mug regardless of this effect not working but either way i was disappointed because it is still a present that didn't work which is why i rated the mug a 3 stars out of 5.

This mug is perfectly functional - it holds a good amount of coffee and it feels sturdy so no complaints there. The delightful surprise the first time someone sees it change color is awesome, and even though I've seen it now many times I am still delighted by it. The color changing mechanism is pretty responsive going the other way too, so sometimes I've used it as a reminder that my coffee is getting cold - "Oh no, my octopus is changing back!" This mug makes for a perfect gift for anyone in your life that loves the sea but also has an intense daily need for hot beverages.

Made well. I absolutely love the color change and it happens quickly black to blue! Great size cup. Is my new favorite!
