- EEG device sellers on Aliexpress react very nervously on reviews about EEG, for instance by increasing costs for EEG caps if we write reviews about those.
- Is there someone who tries to maximize making money out of EEG caps?
- We reviewed the Greentek Gelfree S3 cap in our journal.
- We complaint why this cap is not available on Aliexpress, as other EEG caps.
- Shortly after that, the Greentek Gelfree S3 was available on Aliexpress for more than 1000 USD.
- This is even more than if we buy this cap directly from Greentek.
- Who pays this much for EEG cap with only little components?
- EEG caps can be built from single components.
- Why should some spent this much for an EEG
- We do not know of scientific papers the Greentek Gelfree S3 cap is used in
- The lowest price for it could be found in the OpenBCI USA store
- This is a store which is not known for low prices
- We cannot follow the business plan behind the Greentek Gelfree s3 capabilities
- Does Greentek think they find new customers in Switzerand, if this cap is sold at a high price on Aliexpress so that Swiss have to buy the cap in the US?
- High shipping costs and import taxes are the result
- Does here try someone to make money out of EEG caps, components from wich we do not think that there is a big market for it?
- The result is that we think it is better to build caps from single components by ourselves
