But PiEEG 8 channels was pulled from the market from PiEEG before it has been released:

It was announced for mid 2024 but never came onto the market. It is now available from 350 USD from Elecrow:

This is 100 USD less than it was from by PiEEG. PiEEG for 350 USD with 8 channels costs almost the same as OpenBCI made in China with Bluetooth and WIFI with 8 channels which started from 320 USD on Aliexpress:
We suppose that there is stock marked speculations with OpenBCI made in China and eventually also with PiEEG from Elecrow if they receive positive feedbacks. But the prices for OpenBCI made in China remained stable over several years, since we suppose the sale rate of those where low, and we basically do not know anyone who uses OpenBCI made in China.
