I bought a QPS back in April, I had configuration issues right away.I followed the tech support format and emailed them. Giving them benefit of possibly being busy or email issues I emailed four times over four weeks from seperate servers. They do not respond through support.Now the hardware failed, I repeated the email attempts with no response and have phone support three times in two weeks to give up in Cue after 45 minutes.Now I have a very high phone Bill coming and a useless QPS device that I will eat also.Please don't allow companies like this to thrive, which they all too commonly do in todays market.Buy elsewhere.
