If you like taking surveys this has to be the site for you. There's always plenty of available surveys and the money soon mounts up. You can cash out with as little as a £2 Amazon voucher which is far better than sites that make you hang on until you've hit £20.
This might not be the fastest site to earn money from; and when you claim, it takes a couple of days for the claim to go through. BUT, unlike with some other sites, you don't get cheated.
