CNET have published a review of the RCA Opal (2GB, blue) MP3 player. 'The RCA Opal looks like a miniature plastic body board, with its slightly tapered, rounded edges, and measures 3.5 inches tall by 2 inches wide by a slender 0.25 inches thick. The headphone jack is located at the very top, while a small, yet usable, hold switch is found on the middle of the right edge of the player. The Opal's back is nondescript, except for two holes for the microphone and reset switch (with which we soon became familiar). On the front of the Opal you'll find its 1.5-inch color OLED screen, a menu button, and a four-way rocker pad that controls volume in the vertical direction and track skipping in the horizontal direction. A play/pause button is located in the middle of the four-way pad.'
