Great but not Perfect for My TV

Disclaimer: I followed instructions but I'm not the most intuitive when it comes to electronic mechanics. The extenders were easy enough to understand and position, but I had some trouble tightening all 4 screws/parts enough so that the TV is affixed super well. It is pretty secure but I'm able to turn it slightly so that the left or right side is lower than the other - easy fix, I just move the TV back so it's even, but maybe my tool just didn't grip quite well enough.

Highly recommend!

Converted my 100x100 to 300x300. Saved me from replacing the mount. The included hardware saved me a trip to Home Depot for the TV mounting screws. This was really worth it.
