beautiful and sturdy
Size: 48 inch 2 Tier
The shelf is beautiful and sturdy. The only small complaint are the instructions to put it together are deceiving because pieces were put together for shipping purposes (we assume) but didn't actually go together which took us a few times to figure out. I recommend putting it together off the wall before trying it on the wall so you know what pieces go where.

Cheaply made
Size: 48 inch 2 Tier
I would not recommend this shelf. There are no instructions included - just a simple drawing of putting it together but nowhere says what drill bit size to use for the plastic anchors which are square on the end and not round. In addition, you cannot fully tighten the iron brackets or they won’t alight on the wall to hang the shelf. Each piece of metal piping has part of the black coating stripped off as well. And on top of that, the bottom of each shelf is unfinished and looks as though they used a filler to hide holes in the shelf. Not worth the money or the hassle.

Good shelf to upgrade my awkward kitchen!
Size: 42 inch 2 Tier
This shelf is exactly what I was looking for for my awkward kitchen in my new house. Don't mind the plywood walls (who knows what the previous owners were thinking 🤣) but anyways, we had this awkward gap between the kitchen counters and the stove, so I got a stainless steel shelf to fill the gap and add some more counterspace, and I found this industrial style pipe shelving, which was the perfect size and height to fit in this gap on the wall and give us more storage/organization space. It's easy to assemble and hang up, and seems very strong and sturdy. It's a little heavy, but lightweight enough to hang easily. Right out of the box, it was disappointing to see some scuffs in the black paint on the piping, especially for the price. Luckily, the biggest scuff is in a pretty inconspicuous space so it's not a big deal. Definitely not worth returning to see if another one wouldn't have any scuffs (especially since many of the other reviews mentioned scuffs too). It's wabi sabi I suppose 😅 Also, not a single extra screw or hardware was included. Not a big deal, but screws are cheap enough to through in one extra just in case one is missing or lost. Overall, mostly happy with the purchase. The wood is solid and the shelf looks nice in my kicthen!
