I've done well out of Ipsos Panels and Opinion World. Well, I signed up to a handful at the same time and a few months on I've had £15 in vouchers from Ipsos, £50 cash from Opinion World and the rest I haven't made enough to justify. I don't bother with MyVoice or Rewarded Opinions anymore, and Toluna are ridiculous. They send me about 4 surveys a day and I normally go on and have 1 already closed, 2 I get screened out of, and the other I get about 3000 points on. Which sounds a lot until you realise you need 80,000 points to get a high street voucher. I'm on about 65000 now and going to keep on until I get my voucher and then leave. I recently joined Lightspeed and they seem to be quite good and interesting.
