This is exactly what I wanted
            
            
              I have been searching around for a TV mount that moves forward/Backward and Up/down separately. I spent a lot of money and time to move my Tv around my house to find a perfect place with a perfect height for watching TV and no success until found this MM-Max1. It truly is an amazing, high quality, multi function bracket for over the fire place. Easy 45 minute installation with simple tools and a little bit help from Chatgpt to learn about my TV weight so I can adjust the piston. 
Very satisfied and not planning to move my TV to any other location.
