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

These work great for home office.

Color: Gray, Size: 24" wide, 66" Tall

I was looking for something to block background for a home office, so I wouldn't have to use the distracting background filters. These work great and give my backdrop a more professional appearance. They are very easy to install. The box arrived with a few shipping holes, but packaging was sufficient to avoid any product damage.

Simple and useful.

Really useful and functional. The feet can fall off when picking up but not too much of an issue.
