DO NOT MACHINE WASH
by ComputerGeek (5 out of 5 stars)
April 23, 2016

I bought this back in November (it's now April) so I've been using it daily for nearly 6 months now, and I hand wash it every day, and microwave it every day and have not had any issues with the constellation coating ( or sticker as some call it). EXCEPT, when a mug says "DO NOT MACHINE WASH" in big bold letters at the bottom, do not put it in the dishwasher, even if it's while you're absentmindedly loading dishes. I didn't realize what I had done until I took it out of the dishwasher and it had these weird white spots all over. I don't think they were spots from the soap or the water, since none of my other black mugs have spots, but whatever it was my mug looked ruined. I tried to gently rub them off, washed it, rinsed it, wiped it, but the white spots didn't go away. I still used it every day, though, and the good news is that little by little the spots have disappeared. There's still one faint spot left, but the mug has fixed itself. So if you hate doing dishes like I do, and you find that you absentmindedly threw your mug in the washer, don't despair. Keep using it and it should fix itself within a couple of months. I'm attaching pictures of the mug right after the dishwasher.

Be careful!

I was extremely disappointed in this product due to the amazing reviews from other customers. I bought this as a gift for an astronomy lover. The product worked great, the first time he used it. Sadly the first time he washed there mug BY HAND I must add, the top coat or whatever washed right off. Attached is a picture of the mug after one wash. Not impressed by this brand or product!

I like the mug and it is a lot of fun. My one grievance is that the background doesn't really stay black when your hot drink in it. Take that as you will

Beautiful. No problems. Highly recommend purchasing.

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.

Disappointed, do not buy

The mug is so cool and the heat changing constellations are awesome, but after my second time putting it in the microwave, plastic started peeling off from the rim. My mug is no longer safe for use, which is really disappointing since I've only used it twice. I wish the product were better quality.

Not dishwasher safe
by Author Sable Sylvan (Heather Davies) (3 out of 5 stars)
June 15, 2019

The mug changes color because there's a sticker on it that changes color. The sticker isn't waterproof. The mug isn't dishwasher safe. Even with regular normal handwashing where the mug isn't submerged for long, the edges have started to get gross. The mug takes a while to heat up and change and when it does actually change it happens quickly. You basically end up watching paint dry and when it's finally about to dry, it's a "blink and you'll miss it" type of situation.

The mug does change color as advertised but the effect isn't that impressive and the sticker makes the mug more inconvenient than it has to be. The actual mug is of standard construction and isn't particularly special.

Fun!
by S Martin (5 out of 5 stars)

I love colour changing mugs, so I picked this one up, and it's fun. Sturdy, well made, and I like that when it shipped, not only did it come in a box, but it also had a protective layer over the mug design so it wouldn't get scratched during shipment.

My only complaint? I would have loved it if the design had stopped another 1/4" to 1/2" down the mug from the top. The top bit of the design revealed by the colour change was blocked because it went all the way to top, and who fills their mug that far?

Amazon 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!

Looks a little cheap, but it's a really cool mug. I'm super careful not to put it in the dishwasher. My cup didn't have piesces on it, which was kinda a bummer since I bought it for a Pisces. Didn't have all of the constellations, but it's still a unique cool cup. My husband likes it.

I love this mug dearly but after only a month
by Whitney B (5 out of 5 stars)

I love this mug dearly but after only a month, the protective coating is already wearing off. I don't even own a dishwasher, don't soak it in the sink, I really have been babying this thing and it's still starting to buckle and peel. Boo. ****Update***I'm retarded, the coating is meant to come off. It's working great and I love it.
