Perfect for a coffee bar
Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 3, Size: 15.7inches, Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 3, Size: 15.7inches
These are great for my coffee bar! These shelves are easy to install and came with all the hardware needed. What a great value for your money, especially when you get 3 of these cute shelves. I love how they help organize my coffee bar area and the size fits perfectly.

If the set screws were white the shelves would be perfect.
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 15.7inches
I'd give 4 1/2 if there was one. The shelves thwmself are nice I just don't like the visible little black set screws. The shelves themself look great and are not wobbly at all if you install correctly. I purposely installed the bracket upside down because of the little black setting screws; I didnt want them showing because the shelves are above eye level and the screws are black and I didn't want them showing. But that made the shelf lean amd wobbly so I turned them back over the way they are supposed to be and that made them level and sturdy. I guess I'll paint the little screws.

Game-Changer for My Space!
Color: White, Size: 4 Panel Basic
I recently purchased the Kecreque 4-Panel Room Divider, and it has completely transformed my living area. At 88" wide, it provides ample coverage, creating a private nook in my open-concept home. The white polyester fabric is not only sleek and modern but also wrinkle-resistant and easy to clean—just a quick wipe with a damp cloth, and it looks brand new. Assembly was a breeze; I had it set up in about 20 minutes. The metal frame feels sturdy and durable, and the three extra-wide metal feet offer excellent stability, ensuring it doesn't tip over easily. I love how the panels are connected with flexible buckles, allowing me to adjust the configuration to suit my needs—be it a straight line or an angled setup. This divider has been perfect for creating a dressing area in my bedroom, and I've also used it to section off a workspace in my living room. Its versatility is unmatched, and it folds down compactly when not in use, making storage hassle-free. If you're looking for a stylish, functional, and easy-to-use room divider, I highly recommend this one. It's been a fantastic addition to my home!

Sturdy and Functional
Color: White, Size: 4 Panel Basic
I got this to replace a poor quality divider that I tried first, and this thing is the best! It is easily folded, stands sturdily, easy to assemble, and the fabric looks great. Very very happy with the quality for the price.

Arrived damaged
Color: Black, Size: 4 Panel Basic
Unfortunately, very cheaply made. It arrived with one of the connecting tubes cracked horizontally. Possibly due to bad welding. It is quite a headache to assemble. It was delivered on time but returned for a refund.
