Attached (scaled down) image shows something that doesn't look like the marketing materials, or indeed any other images on the internet.
The pads shown have simply a small disc with 4 foam towers, and a thin layer of foam to cover up the bottom.
As you can see, these (new?) pads have two distinct sensors. The rim (body) sensor is attached to the bottom of the assembly, thus the device has 3 piezo devices. I'm just curious if anyone here knows about this assembly or how it works compared to the "original" mesh pads?
Thanks
