This mug is really fun for any hot beverage!
Its like magic, watching it change color!
I wipe it with a towel rather than air dry becuase you can get these white stains from where the water drips down the side of the cup.(But dont worry, theyre not THAT noticable)
It does say not dishwasher safe and microwave safe on the other side, but it also says Harry Potter, which makes me happy :D
(It will also make a fun 'Thanks for letting me drag you to the movie theater at midnight gift :D)

From the picture on the website, i thought the mug would be all ceramic with the "shiny" finish that a coffee mug usually has. But the mug i received has a different material around most of the outside that has almost a chalkboard feel to it. The two materials on the same surface make the mug look cheap. The outside is also supposed to turn white when hot liquids are in it, but mine turns more gray than anything, and you are still able to see the white words which are supposed to "disappear". I thought maybe my coffee just wasn't hot enough to fully produce the awesome disappearing word trick, so i was going to put it in the microwave, until i noticed that it is not microwave safe. If i had not thrown the box away, i would have returned the mug. Now the stupid thing has grown on me, but i am still very disappointed that it is not at all what was depicted on your website.

Comments about Harry Potter I Solemnly Swear...Mischief Managed Heat Transforming Mug:

This idea behind this mug was pretty awesome and I immediately wanted it when I first saw it on FB but the cool part is actually some sort of wrap applied to the mug, it is not part of the mug itself. After just one (hand) washing, the wrap started to come off. It is so cheaply made and I'm really sad. Cool gift, cool idea, but very cheaply done. Sorry, do not buy this. I wish I could return it

        White letters are coming off after just 1 wash with a sponge and dish soap. "Mischief Managed" is dull, not easy to see.
        Looked like fun. Bought it for my daughter as a Christmas gift. We're both disappointed.

              Comments about Harry Potter I Solemnly Swear...Mischief Managed Heat Transforming Mug:

              Gave gift to adult daughter and she loves it! Matches photos on non-mobile site by changing to cream. Mischief Managed phrase is clear to read and obvious. "I solemnly swear.." message remains visible even though mobile site photo shows it disappearing. My daughter did not know that some photos show this phrase disappears, and she's very happy with the mug. The phrase change is very quick when hot coffee added - and as quick to disappear as you drink. It's quite the conversation piece at the office! Very unique. Very happy.

                    Love how it transforms with heated liquids but I wish the text was on both sides of the mug. The mug was also a lot smaller than I expected it would be.

                        I was advised the mug had shipped 4 days AFTER it actually was sent. UPS was given instructions to get my signature before leaving the package. Since I live in a secure building that turned into a big hassle for me.

                        Great gift! Bought it as a graduation gift for a Harry Potter lover and she really enjoyed it! Looks a bit plain but once you pour in some coffee, it starts instantly changing. Eye-catching with the two-toned art. Great representation of the map ;)

                        I did want to leave a gift note but the gift note was on the packing slip separate from the box. Might as well not have put it as a gift since I received the shipment and wrapped it myself. Oh well. Still great!

                          This product does exactly what it describes: the mug is black and displays the first message, then when a warm beverage is added, the mug turns a cream color and "Mischief Managed" appears. My dad was very happy with his present!
