Works well for sockless look, but annoying branding placement
Color: Matte Black, Size: Medium, Color: Matte Black, Size: Medium
The Good: works great as true no show socks for loafers. Gives you that sock-less look that many “invisible/no show socks” don’t provide for loafer type shoes. I really like these socks because it works for that purpose and they don’t slip off. The Bad: I hope Ondo considers my review, because although I love the functionality of the socks and would like to buy more, the only thing that prevents me from buying more is that they put their logo right at the heel of the socks. When I’m driving and look down at my shoes, the ONDO branding is very apparent and it’s quite annoying (I bought the black color socks). I’m not buying more pairs because of this one gripe I have with these socks. Other than that, these socks work well. Just too bad the branding placement of the socks is annoying. Will keep my current pairs but won’t buy more.

Hole after 3 times wearing them
Color: Cream Beige, Size: Medium
While these fit well and stayed up, after three times wearing one of them has a hole in it already. Not worth the money

Good Product
Size: 3 Panel-102'', Color: Beige
I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.
