The Unemployed Philosophers GuildHeat Changing Constellation Mug - Add Coffee or Tea and 11 Constellations Appear - Comes in a Fun Gift Box

Anthony Wesley2/9/2018Amazon Product Review: Color-Changing Mug Recently, I purchased this color-changing constellation mug from Amazon. I absolutely love it!. I decided to buy this mug for my beautiful girlfriend, who loves to look at stars every time we walk outside. It was part of a Christmas gift for her. I am so happy I bought it. I would definitely rate this product 5 out of 5 stars.Overall:To evaluate this product, I used simple criteria. One: the insulation of the mug. With this specific mug, I realized that it was a great insulator of heat, keeping my girlfriend’s coffee warmer for a longer amount of time than her average $3 mugs from Walmart.Appearance:Another criteria of judging I used was the overall appearance of the mug. This specific mug aside from it’s amazing color changing qualities, has a very smooth and shiny seal all over it. Making the mug easy to clean and easy to hold. When you first see the mug, it looks plain black and has stars all over it, even the handle. When you put hot liquid in the mug, (ie: coffee, hot chocolate, tea..) the entire mug changes color to let the owner see constellations clearly outlined all around the mug! The effect of the color-change is extremely fascinating overall.Functionality:It totally brings the mug to life in a fun way. Using this mug makes waking up early for class or work an even better experience as it wakes you up and reminds you of something amazing, the stars and constellations. As the liquid cools down again, the mug changes back to a plain black color, making it also reusable. The negatives about this product are that the handle of the star mug does not change color, but scientifically it makes sense why it wouldn't. The mug also is preferred to be hand washed only. I understand why it is not machine washable because it is so sensitive to heat, but it does make it a little more cumbersome to clean.Utilization:Lastly, I think this mug is perfect for those who live in cold weather (and enjoy hot drinks), or college students (who are fueled on coffee). This mug would even be perfect for learning children as when the constellations appear they also have names to go along with them so they understand. There are also nontraditional ways yo use this mug. I have commonly used this mug for the consumption of ice cream and it works perfectly when I also want to cool off on a hot day.My girlfriend drinks coffee at least 5 times per week, and she uses this mug as often as she can! I strongly recommend purchasing this mug!

I absolutely LOVE this mug! I love looking at the stars on a clear night and when I saw this mug, I decided to buy it. It arrived quickly and in one piece.When I first used it, I didn't realize that there was a protective film that needed to be removed so I thought it was ruined. That was my fault. Just remember to remove the film before use.Some of the low star reviews relate to damage after putting the mug in a dishwasher. Do not put this mug in the dishwasher! The bottom of the mug states that it is not dishwasher safe, so any damage by the dishwasher is not on the makers of the mug. I just wash hand wash my mug after I am done using it and do not have any problems.I very much enjoy this mug. It is a little more pricey than most, but it's beautiful and worth it. It is so fun to see the constellations appear when your beverage is hot and disappear when the beverage cools down. I highly recommend this mug as a gift or as a personal purchase.

Bought this as a gift for a friend who loves to star gaze, they loved it! The color changes when you pour a hot drink in to show the constellations, worked great.

I bought this as a Christmas present for my wife. I was a little worried about it arriving broken, so I made sure to order it with plenty of time to spare. Thankfully, it arrived without a single nick or dent.Now that my wife has had a chance to use it, I think we can both safely say that we love it. I'm a little disappointed that the sky ends up turning gray when the constellations appear with the hot drink, but that wouldn't have changed my decision when I was buying it. It's a hand wash only mug, which could be aggravating, but I understand why, and it's not a hard mug to clean, so I'm not annoyed by that either.This isn't a mug that you get just to have a mug - the price doesn't justify that. This is a mug that's meant to be special, not shoved among the other mugs. This is a mug meant to be something that makes you smile every time you pull it out. If constellations don't do that for you, I suggest finding a different mug. Or, if you just need a mug for the sake of a mug, head to Dollar Tree or Goodwill instead.Good sturdy mug, durable, and just plain fun. Well worth the price, and it made a great present.EDIT: Like others have commented, after a bit of use, the sticker started peeling off. We only ever handwashed the mug, and tried to be very careful about how we washed the outside of the mug, but it still happened. It only was a little circle the peeled off, just about as big as one star. So we immediately decreased the use (we went from using it almost daily to hardly ever) and tried to be even more careful in an attempt to preserve it. This happened to us just a couple months after we got it. We still love the mug and it's still functional even today, 4 years later, but the sticker WILL peel off. It's not a matter of that being careful will make it into an "if" it peels off. It will. You can't fight it.

High quality, attention to detail, constellations are easily recognizable and legible.

The mug works fine and doesn't have problems.It is exactly what it is - heat-sensitive tech on mugs is always gonna be fragile. Don't put it in your dishwasher; don't microwave it. Hand-wash it. It'll always show a big of grey when heated. These are things common to mugs like these unless you get a reaaaally expensive one.

Le lave-vaisselle ne l'a pas épargné.

I purchased this as a gift and it was very well received! It has been enjoyed a few times now, and we both like to look at the constellations that come up on it when it's hot.

Interessante e particolare come regalo
