A unique and solidly built tool that is only worth searching out on the used market. Other than improved build/material quality, this one also has upswept weight horns for plate retention that I've not seen on competitors' units. There are plenty of options for dorsiflexion without a machine, but none offer the ease, convenience, and loading capabilities. Anyone that has dealt with lower leg injuries will attest to the need for this exercise. It's also great for ankle strength and stability for those stuck in rigid boots via work or sport.
