The series mode design sold by Brick Wall is licensed from the inventor, J. Rudy Harford. I have discovered Harford's zerosurge.com site. He is selling the same units with slight cosmetic differences. Brick Wall only sells direct. Zero Surge sells direct and does dealerships, so your local Mac store can get in on the action. I haven't compared the prices.
On Harford's site, scroll down to find a list of topics. I can recommend the president's message and Telephone Line and Cable pretection. What a can of worms it is to reliably protect these openings into your computer! I can't grasp all of this on first reading, maybe partially after some study. Ignorance is bliss unless you get zapped. It would seem that the Optilator eliminates this can of worms. Again, there is much over my head in the inventor's discussion of his technology. The specifications list its data transmission rate at 38.4 Kbps. Is there an electrical engineer at the university who can read the Optilator technical discussion and the telephone protection section on the Zero Surge site and render a layperson's explanation and an opinion?
