FistBang is a nonexclusive content site, which means that you may come across the same content on almost any other fisting site. At least there aren't too many fisting sites out there, so exclusivity may not be a huge concern.
There aren't any videos on the website, but there are 15 sets of pictures. Strangely, only a few of the galleries feature fisting scenes. The other ones have fingering, posing, stripping and stuff like that. The photos vary in quality, but some of them are high-res.
In terms of extras, members get access to links to live cams, video feeds, games, jokes and many bonus sites. Some of these additional sites are quite good and feature some HD-quality movies.
The site probably isn't worth your time if you're looking for fisting fun, but those with a wider range of interests might appreciate the extras. On its own, it just doesn't deliver enough.
