U GIVE STARS (https://www.ugivestars.com) is a new Shopping Assistant. It allows users to see ratings of eCommerce websites (reviews that were left by users just like you). As result, you can easily know what websites are safe to order from and the websites you should totally avoid. It also lets you leave your reviews, so that others could benefit from it.
Moreover, U GIVE STARS gives the ability to keep track of purchases from different web stores.
And the best of all, this service is completely free.
