Just opened a cafe that serves panini from 11-4. We're currently doing about 30 to 40 panini. We bought 2 warrings that have a 14x14 griddle. We are not quite in our busy season yet & have only been using 1 press. It WAS working great, but 2 months in the top plate stopped heating. We unpacked the second press to get us through the week, only to discover the second (brand new press) is not getting hot enough. Warring says to send them back to them, but we need a press ASAP and don't want to buy another warring. ANY recommendations on a press that can keep up?
