Buttslammers 18 continues director Bruce Seven's highly successful hardcore series dedicated to striptease, erotic dance, and toy-intensive all-girl action. A full-motion menu allows viewers to preview the action, then jump to the beginning of each of the disc's four sex scenes; pressing the "skip" button on the remote control or programming in specific chapter stops will allow access to each of the vid's 15 total program breaks.

Special features include Dolby Surround Stereo, a hardcore slideshow, four trailers for other NuTech titles, and "bios" of the starlets; info is limited to the age, height, weight and measurements of the girls, but there is a hot button with each bio that allows the viewer to jump straight to the starlet's scene. PC users with a DVD-ROM drive and an Internet connection can access the NuTech Website directly through their computer.

Perverse Addictions throws a few men into the mix; Seven himself hosts Vol. 1, interviewing some of the stars before their scenes. Both volumes share most of the DVD extras found on their buttslamming companion, with minor differences; PA1 boasts 19 total chapters, four of which are accessible from the disc's main menu; PA2 has only six chapters, but all of them are readily accessible via the menu. Neither volume includes hot buttons with its star bios.

All three titles are unencrypted and all-region compatible.
