Well, I'm new here, at least at being able to post . But, I just received the Revolation Delta, and used it for the first time today. I am impressed so far. I use El Rey exclusively and the only thing I changed temp wise on the machine was when it was in temper mode I raised it from the factory setting of 88.7 to 90 degrees. The set melt temp is 108 and that is in the range that El Rey recommends. My molds all look great, but will find out tomorrow when I fill and seal them. I was rather surprised at how quiet it is. I had heard that a lot of the smaller machines were really loud so I was worried about that. But, hardly any noise. I had issues about spending that much money, but I needed a machine to help me with production, and will just hope things keep going as well as they did today. I was more impressed with this machine being computer controlled with a fan for temp regulation. Some of the ones I've read about use a light bulb for the heat source. I have no idea about customer service yet, so I can't comment on that.
