About a month ago, received by mail a letter from them, 5 crispy, just off the press smell one dollar bills. Few days later, answered their call, only because the letter said someone would call. After a short survey, was told I would be hearing from them again shortly, and would send me ten dollars. lol, can not remember but think we got that to. Last night, another call, asking for us to participate in another survey, but the requirements a but different. They are to send a small box like thingy, to hook up to tv. Along with 2 monitors for us to wear. This has some sort of detector inside that will collect data as to what we watch and listen to. Short story- more money to follow, and $50 bonus at the end, with other possibilities for future cash. I had I not known who they were and how long Nielsen had been around, would never agreed to do this. Still, have done some research, a legit process, and they do deliver as promised. Anyway hubby not to koser on this, so he may not participate. I figure what the heck, a tad of cash is always nice, and my privacy has been so violated over the years anyway- and for free - I will give this a whirl! So, just wondering have any of you ever done this ?
