In my opinion dooyoo is the best site for earning money online. It is very rewarding as it gives out 500 dooyoo miles for a review of over 150 words which does not take very long to write.
500 dooyoo miles is equivalent to 50p and considering most other sites, such as ciao, only pay a few pence for each review and that is only if people rate is as helpful.
I only heard about dooyoo through ciao as i was a member on ciao first. It was a bit annoying as it was harder to earn money but i saw that several members were also on dooyoo aswell and it was easier.

In my opinion, dooyoo is much better as it actually rewards people for giving their true opinion and it is quite fun telling people what you actually think of a certain product.
Also, i think ti is better that dooyoo cares about the quality of the writing and blocks the accounts of people who just copy and paste material.
It is teh most rewarding online site, great for informing peeple and the money nice too. I just wish the cheque payout limit was a bit lower.
