Back Strap too Loose
Size: 8, Color: Platina
Pretty shoes, but the back strap felt so stretched out I couldn't really wear them. It would have been effort to walk in them.

Great office space divider without being suffocating
Color: Black, Size: 4' Wide x 6' Tall (Fluted)
This is a nice option for dividing up your office space. It's lightweight enough to be moved when needed, but large enough to create a sound and sight barrier between desks. The window design at the top also allows light through so that you don't like you are boxed in.
Overall, this is a great office divider. It's well made, large enough to make a difference, and portable if you need to move it. And it does this without making you feel like you're in a box thanks to the fluted clear window at the top. It does the job I need it to.

The Hush Screen Portable Office Divider has been a game-changer for my workspace. It not only adds a touch of privacy but also beautifully separates the area, creating distinct zones within my office. The divider's design is functional and modern, seamlessly fitting into my decor. Its portability allows me to reconfigure my workspace as needed, adding an element of versatility. Setting it up was a breeze, and it was sturdy enough to stand on its own. If you're looking for an effective way to enhance your office layout, this divider is a fantastic choice. I can definitely recommend it!

Light commercial grade quality
Color: Black, Size: 4' Wide x 6' Tall (Fluted), Color: Black, Size: 4' Wide x 6' Tall (Fluted)
This VERSARE hush screen portable divider appears to be well made and of light commercial grade quality. The lightweight aircraft aluminum frame and black fabric panel aren’t as heavy duty as the commercial grade steel panels of years past, but this panel certainly has adequate durability for home or office use. The sleek modern style is aesthetically pleasing, definitely appropriate for commercial applications, it doesn’t look cheap, or out of place.
It’s freestanding and portable, with optional locking wheels, measuring 4’ wide X 6’ tall. The top panel is made of a clear fluted fiberglass, providing a window for natural light to filter through. I’m currently using it in my home office to partition of a separate workspace for my college student. It works very well for my purpose, I now have two relatively private workspaces in one office.
It’s fairly easy to assemble, but the instructions could be more detailed and illustrative. One thing that I don’t like about it, is that the legs only slide in place, but they don’t bolt to the frame, allowing the legs to slide out of place when the panel is lifted up. The problem isn’t as magnified with the wheels installed, because the panel is then rolled, rather than lifted. It would be much easier to lift and move if the legs were bolted in place. But since I won’t be moving the divider very often, it’s not a deal breaker.
Overall, I’m very pleased with the quality and look of this portable divider. At just under $555, it’s perhaps a tad bit overpriced, but still a reasonably good value. I recommend this VERSARE portable divider for home or office applications.
