One of the things I notice with the PT2 vibration is that it’s a distinctly higher frequency than the PT and PTS.
In fact, in fact, it seems it’s at an audible frequency Hz, as opposed to a vibrational Hz.
Vibrating so fast that I often miss it. I feel if the vibration was lowered a bit and the pulses were not as “soothing?” but rather more staccato, it’d be more noticeable.
This will probably also be very important for the PTR2- which is considerably thinner than the PT2 and likely have a less affective vibration.
