We previously have found out hardly anyone buys PiEEG:

Or uses the PiEEG forum:

We previously speculated about issues about PiEEG which could be the cause for this. Now William Croft commented in the www.openbci.com forum about PiEEG:
„The PiEEG has a Github I believe. AJ Keller’s project never produced any products beyond his prototype. Not sure if AJ even had the software to drive the board. PiEEG comes with software.
For safety reasons, any EEG system should be either battery powered, or comply with IEC 60601 medical standards. Neither of these board comply with 60601. Nor does OpenBCI, but those boards ARE battery powered.
I would be cautious with the PiEEG design. Some previous noise measurements I’ve seen, imply that they may not be complying with Texas Instruments “star ground” / multi-plane design standards (shown in the data sheet). And PiEEG recommends you connect the Pi digital Ground pin to the client. (As a noise reduction workaround.)“
