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.

Instructions are useless

Size: 1 Panel

The instructions are poorly written and not very helpful. The divider itself is easy to assemble, and honestly, it would’ve been quicker if I had skipped the directions altogether. Once put together, though, it works as intended.
