The staff don't know what they are selling, the limitations or capabilities of the devices. The devices don't live up to the hype, I wouldn't recommend them to anybody, they seem cheaper than better alternatives but quickly cause far more hassle than they are worth. And then when you do eventually exhaust their promises of different devices actually doing what the first one was ment to do, leaving comes with a very large price tag. Just con artists trying to defraud you out of your money.
