Heat Sensitive Color Changing Mug - Add Hot Coffee & Tea and Watch a Unique Battery Change Color - Cool Design Drinkware Ceramic Cup, Cute Birthday Christmas Gift Idea for Kids Mom Women & Men

This product is what it says it is! I was skeptical so I purchased one via Amazon (because Amazon has an amazing refund policy) and it came as quickly as it could, even with all that's going on around us. I immediately washed the cup and used it the next day. I've been uploading videos via SnapChat of it's use and all of my friends adore and love watching! The battery still goes to full even when I poured 7oz of hot liquid into it. Would highly recommend if you're interested in temperature changing cups.

I love this mug but the white edges on the battery outline is easily scratched off

This is a fun cup, a little small for tea with a tea bag. I would buy it again to see the battery light up as the hot liquids go up.

Very disappointed. Color changing ceramic mug isn't color changing ceramic its a sticker stuck to the side of a average black ceramic mug. The sticker was also applied crooked. If be afraid to wash the mug afraid the sticker would come off. Not what I was expecting at all.

It's alright! It works!

Two small gripes about this otherwise very cool mug.1. There is a hole in the cereamic glaze. Just a small white dot against the black finish.2. The image shifting decal was applied slightly crooked. It's a small detail but bugs me.Otherwise, this is a cool little conversation piece that works great!
