It is a pitty, that the Aliexpress Shop2956052 Store does not stick to the unspoken rules of open source hardware:

We observed that costs for EEG components fluctuate strongly on Aliexpress. For instance for this EEG cap:

The costs have strongly risen since we last time saw it, altough we are skeptical about the quality of this EEG cap. Are there any sellers on Aliexpress who want to find out how much money they can make out of us? We would like to inform those, that we do not have an association with Prof. Dr. Giacomo Indiveri, Institute of Neuroinformatics (INI) at ETH Zurich and the University of Zurich to find out how the brain works:

we do not have a lot of money, and we will not buy from sellers who want to find out how much money they can make out of us.
