In the Philippines, we usually refer to the press on the left (with the adjustment knob on the top-rear of the press) as a standard press. We refer to the press on the right, with the adjustment knob at the center on the upper platen(edited: Over the Center Pressure Knob), as the English version.
The English version is said to be more durable and easier to press especially for women. The standard press is harder to press down. However, recently, the argument turns and some say that the standard press (with the adjustment knob on the top-rear) of the press is actually the more durable design.
For those who are more familiar with heat presses, the construction not withstanding and focusing only on the location of the knob and why it is designed that away, is there really difference in durability, ease of use, etc?
