These new EEG modules remind us a bit of the OpenBCI modules which are sold on eBay and Aliexpress, which came onto the market in 2021, as mentioned here:
But it seems only view such as Peter Gamma from www.petergamma.org:
seem to be interested in those, who has neither bought or tested a significant amount of these EEG modules. And for the OpenBCI modules which are sold on eBay and Aliexpress, it took around 3 years to have information about those, their issues, if they are stable on the market, etc.
Other devices which are based on the ADS1299 EEG chip disappeared again, for instance HackEEG. And the same could happen to PiEEG. Neither PiEEG or the OpenBCI modules which are sold on eBay and Aliexpress offer demo products.
And we invite you to test those and write about it in the PiEEG forum. Elecrow has a 30 days money back warranty. You can send the modules back without indicating a reason.
Information for product sellers who do stock market speculation and scalping with products mentioned by Peter Gamma on www.petergamma.org

According to the little experience of Peter Gamma from www.petergamma.org, many of the products listed here are still full of issues which need to be resolved. If you do stock market speculation and scalping with those, you will loose Peter Gamma from www.petergamma.org as a buyer of these products and as a reviewer. Is this not risky? Will you not loose a majority of your costumers as well?
And is it not so, that society in general does not accept stock market speculation and scalping with products as those which are listed here? And will you not be politically incapable of finding a majority of the voters if you do stock market speculation and scalping with these products?
And as a consequence will you not be condemned and punished by a political referendum soon? Especially if you do this to a Swiss, since are not majority of Swiss against stock market speculations and scalping with people on a budget? And people in Switzerland are known for a lot of political referendums, since we have direct democracy in this country.
And Peter Gamma from www.petergamma.org will fight up to the European Court of Human Rights against people who do stock market speculation and scalping with the products which are mentioned on www.petergamma.org. And if they do not have yet the legal basis there to do so, he will fight for it.
What is a scalping?
Scalping is a trading strategy in which an investor buys and sells a single asset multiple times throughout the day. The goal of a scalper is to make a small profit over a large number of small trades, rather than a huge profit on each individual trade.
What is a scalper?
A scalper is someone who buys something and resells it at a price far above the initial cost. For instance some says: “He got theater tickets through a scalper”: Someone who buys tickets to an event in order to resell them at a profit. And is it not also scalping if you take reviews from this site to make out of it a new product offer, and sell it for a higher price? We doubt that you will be successful with it. Since Peter Gamma will review your product and will user not come back to www.petergamma.org after that?
