Nice once put together.
Color: Black, Size: 88"- 4 Panel
I really enjoyed these ones. They got put up, putting them together was a two-man task and not very easy at all. They work really good. They're very heavy duty. You can hang things on them. I kick mine out of the way and they work like a charm!

Very Happy!
Color: Black, Size: 8 Panel
I needed an affordable way to add privacy to my porch due to a neighbor. Not only did this come in faster than expected, it was perfect. I needed more height and easily found a way to add it to this panel. Im very happy with the product and shipping speed, thank you!

Privacy is Us
Color: Black, Size: 8 Panel
This is a great blocker of the sun and neighbors. It's stylish and can be secured. We used wire above and cinder blocks below. Its sturdy in the wind and rain. We love it.

Ideal para espacios pequeños y con estilo
Color: Black, Size: 6 Panel, Color: Black, Size: 6 Panel
Como muchos saben, los apartamentos en Estados Unidos suelen ser pequeños y con poco espacio para guardar cosas. Yo tenía algunas cajas en una esquina que no sabía cómo esconder sin que se viera desordenado hasta que encontré este biombo, y fue justo lo que necesitaba.
Me encantó porque además de tapar lo que no quiero que se vea, le da un toque bonito y moderno al área. El color negro combina con todo y se ve elegante sin ser llamativo. Es liviano, fácil de mover y guardar, y lo mejor: no ocupa mucho espacio cuando no lo estás usando.
También me sorprendió que se siente firme y bien hecho, no es de esos biombos que se tambalean o se ven frágiles. Ahora tengo más privacidad y orden en casa, sin tener que hacer grandes cambios. Una compra sencilla pero que hace una gran diferencia. ¡Lo recomiendo!

Easy setup
Color: Black, Size: 8 Panel
Very simple to put up. No assembly required. Just take it out the box and you're done! Also I thought it would be heavy. Very light and easy to move😊
