The insert weighs 540g, measures 15.5cm overall and has an internal length of 13.5cm. Its peanut-shaped body shares the soft version's mold. The exterior is noticeably firmer, approximately +1 on the review's scale, making handling more stable. The dark-red inner layer is around grade 0, not equally hard. Oil release is low, with odor mainly present just after opening.

The channel repeats the soft version's design: three large adjacent longitudinal reliefs at the front, followed by irregular anatomical-style textures. It tapers strongly from a broad front to a narrow rear. The hard sample did not show the same texture damage noted on the soft version.

The front reliefs act as mild speed bumps rather than major obstacles, favoring comfort over high intensity. Yet the broad front is difficult to evacuate of air, while the rear is very narrow, creating uneven enclosure. Firmer material fixes the texture in place and reduces the soft version's movement and responsiveness.

The original rating is 3 stars. Main limitations are the broad entrance/narrow end combination and loss of dynamic texture. The source's second-hand manufacturing explanation is not a verified specification.
