I still wanna write a blog about how to choose the right size of rosin press kit between 3x7″ and 4x7″. However readers is easy to be confused by my poor English. Now welcome discussion here, Thank you guys! 1, Without caged frame, just setup by screwdrivers. It means it is a little bit hard to align upper and bottom plates. Unless you align each time. So both of sizes isn't good enough. 2,Usually we won't place buds/rosin bag in the center point of heating plates instead edge of plates for watching oil flow. 4x7 will take more time than 3x7 so dab is not pure. We will also lose some pressure cause buds/rosin bag position. 3,4x7 size is more spend on freight cost than 3x7 in the same condition. 4, 4x7 is slow heating than 3x7 I don't wanna tell someone ours is the best here. I do hope we can improve our quality under your help. Welcome to tell me truth, Thank you!
