We do not know of any independent testers who tested these devices. We do not know of any users who confirm that they use these modules.
But market stragedy is obvious. They seem to search for market shares. And the costs for the most affordable devices for 8 channel devices seems to be linked to the costs of 8 individual TGAM modules.
This is something smart to gain market shares. If the costs for the most affordable 8 channel devices rises, costumers who are looking for the most affordable device would choose individual modules, and the market shares drop.
Also the costs for the modules seem to be random. It looks as if someone is evaluating who much money users are ready to pay for these modules.
View of these modules have been sold already, as you can see in the shop selling rates.
We did not control the different OpenBCI Aliexpress stores for user confirms who confirm that they use Aliexpress OpenBCI modules and confirm, that they are working.
Most OpenBCI modules seem to be available from these sellers, but we do not know of any documentation and user community which is independent from www.openBCI.com.
