As someone who runs a magazine site www.in2town.co.uk and someone who has worked on both sides of the coin which includes in a public relations company and working as a writer for a glossy magazine, i would say you are doing a good job with your marketing by working with sites for reviews.
By offering review products, you are getting the attention of magazine sites and if they accept your product to review and like it and give you a good write up with a link then you will gain customers.
We receive loads of emails each day asking us to review products, we even had one on friday who offered us money to review the product but we are very choosy on what we review.
I would also suggest that you look for a site where you can offer them a prize, and here is me putting my pr hat on. I would suggest you look for a site where you can run a competition such as a deserving mum etc as this would give you lots of exposure.
If you need any advice then pm me, but look out for special dates and try and get websites to take on your product as a prize as well as getting other sites to review your product.
The more sites that review your product and give you a good review, you will be able to say that your product has been in that publication on your site
