Excellent product, very solid, fully adjustable (up-down; side-to-side; tilt up-down). Holds the weight of our 65" Samsung without sinking. Tighten or loosen the arms/adjustments at the back to suit your application (small wrench). Because it is fully adjustable, the wall plate does not have to be centered on your TV - important for us because we installed on a concrete wall with an immovable wall outlet where the plate would normally go. We used 6 Tapcons to secure the wall plate (see picture) - very solid. Not a difficult installation: secure the wall plate, attach the rest of the mount to the wall plate, then lift and secure the TV to the mount - easier with 2 people, especially for the last step. Arrived in 6 days by UPS. Highly recommend.
