Query: Peerless Articulating LCD wall Arm

Excellant Arm, Easy to install, Need 2 people to make sure it is all square. Looks and works well on the wall. The only problem I had with it is the screws they supply with the unit to mount on the wall are cheap and useless, I would recommend buying 2 bolt type screws instead of these philips head screwws that are supplied, It will make your life so much easier.
