Fast delivery and carefree. Installing the Vogels EFW 8305 super easy. Unlike other comments the supplied bubble level is sufficient (check with another spirit level). 4 screws into the TV (Sony KDL-40WE5) and 4 screws to the wall and it holds very well. Although given the number of screws of different size and diameter to fit many different models. Pay attention to the limited depth (25mm) between the TV and the wall as this can limit the USGE of some cables (Problem solved with HDMI cables with swiveling head of Amazon Basics AmazonBasics - flat HDMI cable with Ethernet connection - 2 m [ Free Packaging Amazon Frustration]). Very pleased in all cases.
