I have a similar Peerless mount in my bedroom so after much research I wasn't surprised it was the perfect mount for my project. I spoke to Peerless a few times before placing my order and even asked them to send me a PDF showing the angle that wasn't in the instructions to help me plan. After receiving the product, I was able to install it MYSELF in about 30 minutes. And most of the time was spent measuring and re-measuring. I'm not sure what the previous reviewer did wrong or had a defective product, but I am very happy with this product. There are a few things to note though: This mount is for applications where you just have a stand in the wall exactly where you want to mount the TV. You need to install it in this hairpin. If you have two studs, Peerless makes a similar mount with a much larger wall mount and a sliding horizontal adjustment that lets you choose the best TV position between the studs (I have this model in my bedroom). Also, forget everything you think you know about geometry and just follow the instructions. All you need to know is where you want the center of your TV to be on your wall. If you're short on space and concerned about the perfect vertical height, I'd recommend leveling the TV, maybe an inch lower than you think. There is a 1 inch upward height adjustment that allows you to fine tune the height after installing the TV. Now that I have this mount installed I can rotate my 40 inch Samsung LED TV a full 90 degrees from the wall. Brilliant!
