No show but stays on
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I wear these socks daily. They truly don’t show with my workout shoes or with hey dudes. But the best thing about them is that they actually stay on your foot. I work out hard and I don’t ever have to pull them up. I do wish they were just a little bit thicker than they are, but they are definitely a product I will buy again.

Worth the investment
Size: 1 Panel, Size: 1 Panel
I had to order this in an emergency. To put it in brief words, I live in a two level studio unit. My bedroom TV fell backwards off the bureau accidentally and down the stairs to its demise. Putting this together was no problem, instructions were thorough and easy. It came with several bars that connected together smoothly and an Allen key for the brackets and screws for the feet. I did one less horizontal bar on top and bottom so it could fit, which was great because with all of them on it was too long. However I ran into the difficulty of the horizontal bars popping out of the brackets during the last stages, but eventually got it done. I was also looking for a specific type of divider where I could adjust the feet so I could tuck it in between the dresser and banister. Glad I made this purchase.

You Get What You Pay For! A Piece Of Junk!
Size: 1 Panel
Flimsy and a piece of junk. Don’t waste your money. Assembly is a pain because it is so flimsy. Divider is thin. You can see right through it. Very wobbly.
