I liked the brain exercises and used for a long time. Eventually stopped though. Saw bill on credit card last year for recurring subscription. Called Lumosity and miraculously spoke to a real person. They refused to remove the charge, but said the would take me off recurring billing. Fast forward one year and they have charged me again. Now, it is impossible to get a real person on the line to discuss this. Working through credit card company to reverse the charge. Despite what I think is a good product, this is a criminal operation and it should be prosecuted accordingly.
