Bests & Worsts Reviews from Amazon

If you've upgraded your Windows XP OS to service pack 3, this device will not run. Worse, after you install the software, Windows becomes unstable and there is no way to fix the damage except to reinstall Windows or do a System Restore to a point before the installation of this device. But what bothers me the most is that Diamond offers NO support. I tried to phone them but there is no telephone contact info listed on their website for tech support. I tried their tech support chat facility for three days and was always told that no operators were online. I tried emailing them and they never replied. This left me feeling pretty negative toward Diamond products in general.
