We needed a way to minimize the space taken up by a 21" TV in our newly remodeled kitchen.  This was the perfect idea to mount it under the cabinet.  We can swivel it to watch it in the kitchen or swivel it to watch it in our breakfast nook.  It is extremely sturdy and easy to install.

Pros: Very sturdy and easy to install.
Cons: The plate is universal from 17" to 37" so when using it on a small TV, the large ears of the attaching plate show.
