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.

        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.

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

            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!

                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.

                  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.
