The heat press is 25 degrees off so keep that in mind when using it… If your temperature calls for 300 put the temperature to 325… Also you will need two heating mats to get the right amount of pressure.. One heating mat most jobs will not come out right.. There’s a slight gap between the plates when closed that gives you uneven pressure with one mat.. Through trial and error I got the autopress working to perfection… I hated the machine at first now I love it!!
