The focus of 247BootyCall is black-on-black action. There are 17 scenes with one-on-one fucking to threesomes of both kinds. You can download the movies in Windows Media format, either in short clips or the entire file. The quality here is average and the site seems very stingy with updates, so don't expect any new content to be added.
Each hot scene comes with a set of vid caps you can use to preview the action. It's helpful if you want to see what you're getting first.
On the bright side, if you click on the Adult Video Planet link, you will have access to a ton of bonus material. Namely, over 100 more sites in many hardcore categories, all with downloadable movies.
Unless you are looking for exclusive content, the sheer wealth of hardcore material and the cheap price makes this site pretty worthwhile.
