    Great cup, but I'm a little wary about its longevity
  

*by S***R on Reviewed in the United States 🇺🇸 on May 16, 2014*

Update:Removing one star. It's been a year since I bought this cup. I use it every day at work and have always washed it by hand. I don't even use a sponge or brush…literally by hand with dishwashing liquid. The white outline of the battery is coming off, and it seems to be coming off faster and faster.I feel torn between continuing to use it and watching it degrade and buying a new cup and taking this one home. But I really don't want to reward their cheap, short-lived decals with another sale. But I really do like this cup!-----------------------------Original review:I really love this cup and I get a lot of comments about it. The basic idea is great.A couple of detractions:1. When I wash the cup, I worry that the image is going to peel off. It hasn't started to, but it's raised off the surface of the cup in a way that most images on mugs aren't. Makes me wonder if one day it will peel off.2. The heat sensor isn't very sensitive, so the green color only lasts a few minutes. The coffee will still be warm and yet the color will be fading away. I wish it would stay green till the coffee is actually cold.Small matters, really. Overall, it's a good cup.

    Worldfashion Battery Color Changing Thermometer Heat Kruzhkus Mug Sensitive Porcelain Tea Coffee Cup
  

*by C***G on Reviewed in the United States 🇺🇸 on June 7, 2014*

I am an old and old fashioned, coffee drinking nerd and I like this Worldfashion Battery Color Changing Thermometer Heat Kruzhkus Mug Sensitive Porcelain Cup, but won't be using it for tea.  I have had these color changing cups before and do not recommend them to be washed in a dishwasher.  The heating cycle slowly destroys the color change after getting too exposed to heat.  Also keep them from the Microwave also if you want the color change to last as long as possible.  Just some experience with this and another cup or two I have had in the past.  Enjoy your cup, nerds.

    Don't put in dishwasher
  

*by D***N on Reviewed in the United States 🇺🇸 on May 8, 2019*

Got this for my brother in law as a birthday present and it is amazing. Still works well after 6mos and he uses it almost every day. Definitely recommend reading the part on the box that says do not put in DISHWASHER though. Accidentally threw it in there one day and part of the outer coating seems bubbly but that was my own fault. 10/10 recommends as a gift for anyone
