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.

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.

      The "I solemnly swear that I am up to no good lettering doesn't fully disappear when a hot liquid is added which is a little disappointing.

          Utilizing the product for drinks. I like to have my own things because the people or monsters here hoard things, steal cheat and lie are lazy. Some of them didn't earn it.

            I have bought MANY of these mugs since they first came on this website. I give them as gifts, and every single person I've given them to has been very happy with them.
            They're well-made, in an easy-to-wrap box, exactly as described. I'll keep buying them.
