Are not EEG caps very expensive if we consider that the single components they are built from generally are very cheap?

  • 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
