I am signed-up to numerous paid survey sites - opinionworld, ciao, yougov, freesurveysuk, ACOP, ISPOS, permission research, pinecone, and so - and I am in the process of writing up an article of my findings. I, however, feel compelled to tell everyone about a seemingly less well known survey site that is quite frankly the best so far by miles.

Vindale Research is an incredible site that is so professional and easy to use it is absolute joy. Yes I am enthusiastic but believe me once you start
using Vindale Research you will be to. The feedback on the statuses of your surveys is second to none and they tell you very precisely all the conditions of each survey upfront, so you know exactly what you need to do to get paid.

Each survey consists of a product evaluation phase - you may have to sign-up to a product trial or visit a product website, and any fees you pay for the trials are reimbursed - and a survey phase, which only takes about 5 minutes to complete. They send roughly 2-3 product evaluations / surveys per week
and when you are sent one you are guaranteed to qualify as you are invited to each based on you matching the entry criteria. Each survey pays between $5 - $75 and you can cash out via PayPal once you have earned $50.

Even better you earn $2 for joining and a further $5 for each referral, once they complete their first product evaluation - i.e. refer 100 people and earn $500!!

This is a truly awesome site that I cannot recommend highly enough and definitely worth joining -it's free! - if you want to make an extra $50 - $100 per month
