Structurally this is very sound, but I only give it 3 starts for a few reasons. The biggest is that the actual product states on the packaging that it is for TVs up to 50", and I specifically purchased for my 55" TV. While TECHNICALLY it does fit, it does just barely and doesn't look quite right as the TV is taller than the stand and exactly as wide. 

The other reason for taking off a star is that it is much smaller than it appears in the picture, especially once you put a 55" TV on it. 

As far as putting it together it is a little difficult and time consuming, but as long as you follow the directions it is fine. 

In summary, do NOT buy for a 55" TV!
