Has anyone else found this to be a poor mug press? I purchased from ebay via signzworld on some of the reviews and feed back i had read on here. On trialling it, the mat was cold about 1" from the edge meaning that it didnt have good results, I was able to just get a mug done by having it right at the top of the other end of the mat, not good if its a full mug print. I contacted them and today received a new heat mat, but its even worse than the 1st! The heat drops rapidly about 1/2 way down! Not good at all, havent even wasted a mug trying it. Have asked for a refund, shall see what happens.
