Stranger Colorful lights 11oz Thermochromic Mug,Temperature Heat Sensitive Mugs Heat Sensitive Color Changing Cup,Unique Gift for Women Men

Very poor quality. It's a sticker or something similar that is applied to the ceramic mug. Then there's a clear film on top of that. Parts of the clear film were already peeling straight out of the box and the design has bubbles near the G and Q that you can see in the pictures. Overall 2/5. It's flawed, but the color change works a little.

True to picture, measurements are accurate, good quality. As durable as a normal mug. Got it for my mom for her birthday, she’s a fan of the show. Worth every penny.

Zero stars is more like it. My review is simple, I didn’t get what orders. Very poor quality. Paint scraped off right out of the box. The lights barely check with boiling hot water and the inside looked dirty, like it was used.

I was pretty stoked to see a color-changing mug, and I thought the design was pretty clever so I was happy to have it. When I filled it with hot water from the tap it didn't change too much, so I thought the water had to be hotter. When I put it in the dishwasher the colors showed up more, but a small bubble under the film (or whatever is applied to the mug to produce the effect or protect it, I am not sure which) popped and it never really seemed to work very well after that. So besides the fact that it doesn't work very well the design is good. However, this product is more disappointment than anything else, so I would not buy it again.

My son loved this. He was so surprised.

This cup was terrible. The decal on it was bumpy and peeling off right out of the box. I could have made a better quality one myself.

The actual laminate/thermochromic coating just does not match the pictures. In a general sense, the design matches; in a detailed sense, it's different - the wallpaper in the background looks different and the font lettering is very different. The coating used is not the coating described. The coating and its application do not look as good as described, either. It's either cheaper materials or a less effective application - I can't say which - but it just looks sloppy by comparison. The ceramic itself is great - the exact kind of sturdy, standard, glossy ceramic I'd expect in a mug. No issue there. It works, of course, as a mug. Color change takes ~25 seconds with boiling water. I boiled water in my electric kettle to demonstrate the change; the speed was not adjusted. Several of the "bulbs" that start out grey and then take on color do not fully transform - bits remain gray. I'm still using it for my morning coffee and handwashing after. I would avoid using the dishwasher due to the thermochromic application - dishwashers can be too rough on them. If the mug I received matched the description as it looks, I'd say $20 is a fair price for a niche fandom item that has both a function and a fun attribute. As-is, though, it feels underpriced - underwhelming for the value.

This mug does work as intended and the thermochromic color-changing effect is pretty fun. When you add a hot drink, the design changes and reveals the colors, which makes it an interesting mug to use and a fun conversation piece. The size is good for a standard cup of coffee or tea, and it’s easy to hold. The heat-sensitive feature works consistently and reacts quickly once a hot liquid is poured in. The only reason I’m giving four stars instead of five is that the overall design looks a little cheap up close. The effect is cool, but the graphics themselves could look a bit more polished. Even so, it still works as expected and makes a fun novelty mug or gift.

Peça mal acabada, cheia de bolhas e falhas. Não condiz com a imagem. E pior que não consigo fazer a devolução, só da erro no processo de devolução.
