I like that it's free, easy to use, has great content for all kinds of armor! The only thing is that there are no customization options available (except for color) so you're stuck with what they give you. For most people this will be fine but if you want something more custom than a basic black or white set then look elsewhere. It was pretty simple to create an account and start posting pictures of your gear as well as links to other sites where you can buy them.
There isn't much else outβ¦
