This survey house rewards you with 'shells' each time you complete a survey, however they don't inform you how many shells you might earn before you start the survey. The shells can then be exchanged for items, but you have to do a lot of surveys before you can use them. I ordered two ebooks from them, thinking these would be mind to keep, however they sent me an email after I'd ordered them saying I had to sign up to an ebook rental site, which had very dubious privacy policies, then I would rent the ebook I ordered with a limited time to read them. Nice quest are misleading in the way they promote the rewards they offer, they also earn a commission for everyone signing up for a membership of the ebook rental providers. They mislead you, take a week to reply to complaints.
