Observations from having this for almost a year now...…..
Still working excellent and with only 2 screws holding at the top super low room impact.
Problems or things I would do different,...all completely my fault,.....its a huge sound reflector, it made a difference in the room for sure as it is a very reflective surface. So be careful with placement.
Same issue with reflectivity due to light...….hundreds of shiney surfaces all in one spot made a difference in my blacked out room, both on screen and out of the corner of my eye...….once again be careful with location.
Would I build another one....YES and I plan on it already......there is no other solution as cheap and easy out there...….just be careful where you put it.
