Heat Changing Ceramic Coffee Mug - Large 20oz - Officially Licensed Doe Patronus Design Reveals w/Heat - Book & Movie Love Gift for Kids, Teens, Adults, Men, Women

I adore this product. The change is shbgme but it’s beautiful. I’m a huge Harry Potter fan and was very pleased. My only complaint is that it “feels” cheap but it was cheap so you get what you pay for. Keeps my coffee hot for a nice amount of time and it’s oversized which I adore. Would definitely buy as a gift.

I may be 75, but I still love Harry Potter! I love the always mug. Great size for my morning coffee.

I guess I should have read description better. This mug is big. It works well and looks nice though.

It is a great size! Only down side is that you have to hand wash it but I don’t mind because I love it so much!

Just got it today. Got this as gift for my fiancé. She loves it. Granted, we haven’t really used it yet. But we tested it out with hot water immediately. Effects start to show in about 1-2 minutes and only showed to where the water is in the mug. Turned out awesome. This is a great mug. Very very light weight, seems very fragile, but time will tell. Great colors. Will add more to the review once she starts using it regularly.

The cup is awesome! Be aware, it’s huge! The patronus is really a sight. Well done!

I received my mug and was excited to see it change colors with heat but unfortunately mine didn’t. Is there a trick to making that happen or did I get a dud? It’s still a really nice oversized mug with a beautiful design on it, just wish it would change colors like it’s suppose to with heat.

It's a great looking mug, nice size, comfortable to hold. My wife loved it. Unfortunately, after about three uses, she heard a slight 'tink' sound while filling it, and now there is a hairline crack around the circumference. That crack seeps water when she tries to use it, rendering it useless. Looking at other reviews from around the same time I got it, I don't know if it's a bad batch or what, but it's very disappointing.

Llegó antes de lo imprevisto, producto en excelentes condiciones y cumple las expectativas, muchas gracias

Llegó intacto pero la caja estaba muy dañada, me alegra que la taza estuviera intacta pero está vez la caja del producto si estaba en malas condiciones
