Review: Wow, were were trying to run an overhead projector with an old rs232/vga cable. The projector would occasionally blink on and off. Installed this (82 foot) cable and bam, perfect. This cable is great.
Review: Had it for 3 months currently it still does it job wonderfully. Was afraid it would be low quality as certain reviews said it barely held for a week
