Good product. Bad customer service. Ordered an "install kit" which is flat permanent wire instead of the curly cigarette lighter cord. 8 foot long. So far so good. Went to install. Needed at least 12 feet. Called customer service. Wanted another 8 foot cord and a coupler. Apparently they only sell the kits with the cord and not separate. Also don't have any couplers. So what do I do? The "customer service" (notice I put in quotes) girl told me to go to the store and buy a wall to phone cord. Ok, did that. Cord didn't work. Went to an office supply store. Bought a cord there. Didn't work. Finally tried a wire that goes from the phone to the handset (not a "wall to phone" cord. Worked perfectly. RJ 22. Called customer service back telling them what I found out. It isn't a "wall to phone" cord, that's an RJ45. She argued with me saying an RJ 22 wouldn't work. I had just tried one 2 minutes ago and it worked perfectly. THIS TIME she told me it was an RJ 11 and nothing else would work. She vehemently rejected my finding that a "phone to handset" cord worked. Said she told me when I had first called an hour before that she had told me an RJ11. She didn't. Kept insisting that an RJ22 wouldn't work after I just proved her wrong. This is what happens when you hire someone off the street that has no tech experience.
