Nickelodeon Invader Zim You're Doomed 16 oz. Heat Changing Mug

Bought this mug as a Christmas gift for my sis in law who loves invader zim. She loves it!

Daughter loves it. Word of advice though do not put it in the dishwasher hand wash it.

EDITED TO REFLECT NEW INFORMATION: After using and washing it a few times, the color-change feature no longer works. I've followed the instructions to hand-wash only, and have only used it at most 4 times in the past few months, as I don't drink a lot of hot beverages in summer, but still, it doesn't have any change anymore.I've held the mug under hot, running water for minutes at a time, looking for any color change, and yet nothing. It's still a mug, so at least there's that, but I really wanted to have the color changing feature. Otherwise, I would have just bought a regular mug for cheaper.-----I love the color-changing feature and it works so smoothly. The mug is a good weight and easy to clean!

My daughter loves this mug. The words appear almost the instant the hot liquid fills the cup. I thought it was a 16 oz. nice larger sized mug. The largest setting on our Keurig fills this mug all the way to the tippy top and that is the 14 oz setting. So, really the usable area of the mug is more like 12 oz. Not what I thought I was paying for but I won't send it back now that it's been opened and my daughter likes using it (it was a gift). Just feel a little gyped.

Who doesn't love invader zim! Great mug. Thanks.

It’s a 10oz Mug! Very neat color change, just not big enough.

This is a small mug but I love it!

My sister loved this mug I purchased as a gift!
