Has anyone tried the Edsets Bluestreak to connect phone?I

I called and talked to Ed, nice guy. His bluestreak will Bluetooth a cell phone to the intercom without using a gps. At $300 plus an $80 splitter it's getting expensive to use a phone. I'm just wondering how well users like it before I drop that much cash. With kids, aging family, and a business to run I need to be able to answer that emergency call now and then.
