I love that it's easy to make your own account, so you're not dependent upon their system or server. The layout could be more user friendly, but not much can be done about that now. My favorite part is how they have very few restrictions on creativity; if there are any rules, they only limit what others may do with them. They're also always adding new stuff that people like! Their pricing model makes sense too. If you want high resolution files at reasonable prices, this is definitely worth checking out! There isn't anything specific that I dislike other than the price. But since they offer such great low prices, most people won't mind paying $5-$10 per file.
