Great room separator
Color: Black
The panels are much longer than we expected! We only needed 3 of the 4 proivided. It's slightly flimsy, but holds together nicely. The screwdriver that came with did not fit the screws, but luckily we had a Phillips head. It's very lightweight. It is definitely a good value for the money.

Room divider
Color: Black, Color: Black
It was much simpler than anticipated. I don't think it's very sturdy and it lacks weight, but it's attractive.
