Review: Just works - Was a little hesitant to use this in a corporate environment since it HAS TO WORK. I contacted the seller ahead because some of the stuff you buy here is very light on documentation. They explained that all the documentation was available online but it was pretty much plug and play. The circuit came right up and has been stable since install.
Review: Five Stars - Worked as expected.
