About Review Fuse
From the site:
Do you want impartial peer feedback? Do friends and family ever tell you what they really think about your writing? Sign up for an account (which is completely free) and get guaranteed peer reviews. For every 4 reviews you do you will receive 3 peer reviews. You may repeatedly re-submit to get continuous peer feedback as you improve your submission.
You’ll also have a chance to rate the reviews you receive and let the reviewers know how useful their critiques are. Through this we learn who your peers are in order to match you up with others who are as helpful and detailed as you in their reviews.
