Beautiful brown privacy screen!
Color: Brown, Size: 3 Panel, Color: Brown, Size: 3 Panel
Why did you pick this product vs others?: The measurements were perfect for what I was looking for.  The length and width are the same as my rattan raised garden bed which I have placed in front of the screen on the deck.  This secures the screen so there is no issue of weather conditions. I have been looking for weeks for a privacy screen at every possible product and combination. and almost gave up when I noticed the measurements of the screen would fit behind my raised bed!  Now I am going to plant some flowers in it.  This is a terrific buy for me.  i am so happy! Looks great: The perfect size, color, and design match my brown deck rattan furniture. Ease of assembly: No assembly which is nice in this hot weather! Room divider: It provides much needed privacy

Very nice item
Really love the look of this bookcase and also the sturdiness of it. It’s really heavy and has great shelf space as well as being tall enough that I can use the top for figurine/collectable storage but not so tall that the items on top are unreachable which is nice. It was a little difficult to assemble with my husband getting hurt slightly when putting on the backer boards but once we had extra hands to help it was easy enough to finish up.

has some positives and negatives
The bookcases are very sturdy and look very nice. The instructions are easy to follow and they are good value for money (compared to other prices these days) The negatives are that the back is hard to have on exactly flush as they should be. The back panel is taped together poorly and is the main reason for the panels not lining up. I made it work with some creativity though. My main issue is that one of the main shelves (part 3) had the holes drilled backward and so you had to assemble it with the bare wood facing out. I will paint this to get a close match. You can't replace just one part and I didn't want to return the 80 lb package and go the refund route
