I picked up one of these up to try out. It gives really good results; I can see the benefit of pressing the mug for longer with much better results for tricky designs.. A mug will be in the press for about four and half minutes, so not really twice as fast just because it's a twin press.
My problem though; I had a few that finished too soon, then I realised that the timer was counting down as soon as I hit the timer button, rather than waiting for it to reach 175 degrees before counting down.
Has anyone else noticed this fault?
