I am very curious on the quality of the rosin with your press or that type vs a t shirt press. Regardless of how much pressure. You can only press rosin so much. I'm curious of color and yield. I still get 20% flower rosin and 50% - 80% rosin with bubble or sift or kief using a straightener. Color difference varies depending on how long cured, how dry, temp and genetics.
It would be nice if there was a low watt press that would be equivalent in quality. Even the straighteners use a lot of watts.
