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.

    I use this mug so much I'm worried I'll break it, it works just as well as the pictures show and the best part is I have a wonderful new mug that everyone else is jealous of! It is perfect and a wonderful addition to any coffee/tea drinker's home!

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

    I received this mug as a gift and I feel tragically misled about the magical properties of this mug. I feel whomever cast the bewitching spell on this mug obviously did not pass their O.W.L. in enchantment. I'm not prejudiced, but I'm willing to bet the caster was a squib or muggle-born. To be honest I don't think this is real magic and is just some sort of trick. The words don't change with action one would expect from magic. I did give the mug one star because it held a hot beverage just fine.

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

      If you are looking into this mug and are looking at other websites, this mug from the HarryPotterShop is the one to get, the mug is all gloss and doesn't have that matte chalkboard like texture for the heat changing factor. It is underneath the glaze of the mug and looks much higher quality than the one that is sold on the Warner Brothers shop site( no offense or anything against Warner Brothers, I just personally prefer this mug over theirs). This mug is microwave safe unlike the WB ones and I have very impressed with this product.

            I bought this as a replacement for the original mug and am very disappointed. It is more expensive but is much less impressive and doesnt turn white but a brown color that makes the Mischief Managed logo look a bit lame.

                Although the original product had a visible film adhesive on the mug, it was much more responsive and turned white. The new version requires very hot water and only turns a light brown.

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

                I was expecting this to be a little different than it was. I thought that the lettering from when it's not in use would completely blend in when it transformed, but can still see the wording. It's still really neat, though, and it's fun to have. It's a very magical experience in the morning!

                    I was so excited for this mug. I had the older one and it changed so well! Unfortunately this mug DOES NOT. The mug turns a light brown color and you can still see all the white writing, making the mug look ridiculous. I'm really disappointed and would not recommend this mug if you're buying it for the "magical changing process."

                    The mug is very cool and does change color and the text of "Mischief Managed" does appear when mug is heated, however, the first picture and the description state the that the "I somenly swear..." text will disappear and that does not happen. Mug will change color but both pieces of text appear.

                          The mug background does NOT change color to white when hot liquids are added (no matter what temperature), so all the lettering is visible at once. The letters are also poorly inked on the mug, and it is very small for the price. Not worth the money at all especially seeing that it DOES NOT work as a "heat-changing" mug.

                          I absolutely LOVE this mug! I bought one around the time it was first on here but recently my roommate put it in the dishwasher so sadly it's been ruined - BUT I plan on purchasing another as soon as it's back in stock =)
