If you've got the writing itch, WGC Shop welcomes you as long as you write a review for them. Once you write a review, you get entitled to win a US$300 Cash Coupon to buy airsoft products from them. I think they are not asking for a comprehensive review, but more of motivating you to give a short and concise review of a product at any product page at their website.

So if you want to give it a shot, just post a review of any item you have bought previously and see if WGC has the same product.
