Perfect for my company's temporary needs
Color: Gray, Size: 72" wide, 66" Tall
My company ordered multiples of these dividers to separate desks in much smaller temporary space we had to use after our offices were flooded in August 2023. (Yeah, I know - just getting around to reviewing them now!) These fit the bill perfectly. Granted a bit of privacy so we weren't staring at the employee next to us. Easy to put together; excellent value.

Okay for privacy, not a sound wall
Color: Gray, Size: 72" wide, 66" Tall
Ordered this for a home office, it is easy to put the panels together, one man job. They look nice, stand up well, and gave privacy and seperation. You can tack a white board to them. These panels have absolutely no sound reducing properties that I can ascertain, so if you are ordering them as 'accoustic" type panels you will probably be disappointed. For making a cubicle they perform well.

I DO NOT RECOMMEND
Color: Dark Gray, Size: 72" wide, 66" Tall
I got this primarily for the acoustic wall feature but it does not block any sound whatsoever. It's just a mobile, overpriced wall. The only privacy it provides it blocking you from view but the same could be done with some cardboard for a fraction of the price. Not only is it not as described but they are requiring that I pay not only to ship it back for return but is also requiring that I pay for the shipping label. So I will be paying around $150 to get my $400 refund. Unacceptable. DO NOT BUY
