Voice Activation Button

Tried using the Blue Voice Activation button on my new Contour remote. It worked very erratically and unreliably. Frustrated I push the button harder, things got worse. Seems the secret is a VERY light touch. Anyone else experience this or is the remote defective?

 Already took the first remote back after 1 day when it became unresponsive and the green light flashed continuously on it. I don't think these remotes are of high quality.

The move forward/backwards so many minutes works pretty slick except when it take me to another screen with "60 Minutes" show on it.[:^)]
