-In this table we can see that brands which advertise their products as low-cost high-quality have competitors from Chinese manufacturers which offer similar products for lower prices.
Components in the biosignalsplux store are 2.3 times more expensive than those offered by Chinese developers and components sold by www.OpenBCI.com are 1.4 to 2.8 more expensive than those sold by their Chinese competitors.
