Deadly funny, HOT SURPRISE, great painting. Recommended for everyone with a "little" sense of humour :-). Colours are really good. Black in "freeze" mode is also fine :-)

When I first saw the mug it was just all black,and could not see the Zebra,s. When filled with a hot drink,wow,what a surprise to see it change colour,and to see the Zebra,s appear.So unusual. I would strongly recommend this product, if you are looking for something unusual.

Excellent quality mug and printing was perfect. I sometimes order one of my own designs to check on the quality and how the designs are printed, and I was really thrilled with how this came out! Excellent quality, printing was perfect. I sometimes order one of my own designs to check on the quality and how the designs are printed, and I was really thrilled with how this came out! It has been in the dishwasher several times and held up perfectly so far, the heat change still functions perfectly. Really impressed with the quality. Colours are good and I'm pleased how my design replicated.
