My Impression
ShadowSlaves looks like an amateur site, with the settings being both indoor and outdoor. The emphasis of the site is pain and humiliation, with the bondage secondary. When it comes to the action, its not a scriped site, and the models are not acting. The gritty realism makes the action more exciting.

INSIDE
What impressed me was the number of updates. Shadowslaves is updated four times a week, so theres plenty of content. The main producer generally stays off the camera, allowing the models to take center stage. The site started around 2003, so the early content is on the light side, but current updates are plentiful.

The models themselves are both well known actresses, and also new faces. The navigation around the site was easy enough, nothing special, but did it's job. The camerawork is not as polished as other sites, but passable. This also adds to the realism of the shoots.

One big plus is that the movies can be downloaded as both 30 or 60 minute streams, or shorter video clips. So you can skip to the bits you want to see. The download speeds were good. Pain and humilation is the speciality here, and the movies do deliver.

What would I like to see?
Better quality photos, more emphasis on bondage(debateable).

Overall
The quantity of material here make it a good buy. There is a mix of normal scenes and very interesting edge play scenarios. The quality has improved considerably since the sites inception.
