Chinese sellers again and again try to sell OpenBCI modules with issues:
And also Ildar Rakhmatulin tries to sell us EEG products with issues:
The mantra we have heart about this topic is that sellers are not able to lower to costs for those products. And now they sell modules with issues? Do these sellers want to see if there is a market for those?
Stellarpower in the www.openbci.com already reviewed such products from Aliexpress in the www.openbci.com forum. But would it not be better to to it somewhere else?
What for us personally is most interesting ist the OpenBCI WIFI shield. It is available now from eBay and Aliexpress. And also the orignal version had issues. And it was pulled from the market because of these issues.
But there is an instruction available how to repair it. You can find it here:

www.openbci.com without a WIFI shield is for us like a Citroën 2 chevaux
A device which lacks of speed.
The Wifi shield was repaired previously manually. Why should it not possible to repair it again? And then we have again www.openbci.com with full Wifi speed?
