This would be a great product if there was a slot in the top of the extensions to properly mount the antennas. With no slots at the top, the extensions moved everywhere every time I moved the remote. I just can't understand why this obvious question was overlooked. I had several different brands and they all had slits at the top and bottom that held the extensions securely in place. If there's a reason this particular brand decided to omit the extra slot at the top, the explanation remains a mystery to me.
