I am an on/off user of this product, think i have purchased the first subscription in 2008, when their prices were a bit steep (i. E. Eur78pa), then again in 2012. I recently got another package at half that price and bottom line is that i have no complaint whatsoever. I was surprised to read all the negative feedback on this product; i don't play their games every day or even week as they'r tend to be a bit doll so i didn't get addicted to them; but i've definitely noticed some cognitive benefits and overall i take it that the monthly price i pay (from the41Eur pa offer) is bearly the price of 1starbucks coffee, so no real worries here!
