Very nice kit: Beware it is NOT heavy duty plumbing pipe though!
Size: side table leg
I want to give this kit a high rating, but I need to address the "truth in advertising" bit since there may be an important disconnect between what you think you are getting and what actually comes in the box.
Black plumbing used for shelving or table legs is part of an important niche in interior design. I like the industrial loft look myself and have a variety of glass, steel, and masonry elements in my home. This kit fits that look and provides plenty of "strength" for most domestic uses, like shelves or coffee tables. But they are NOT "industrial pipe" or "maximum durability pipe." Note the phrase "cast iron finish feet," which together with the other claims might lead you to think these are cast plumbing fittings. They are NOT!
The feet and flanges feel like electrical conduit fittings, and the pipe sections are likely aluminum. They might be electrical or they might be multi-use, lightweight pipe.
While all this might lead you to think that you're getting a truly retro, heavy-duty pipe kit made of black plumbing pipe, you are not. But, does it matter? Depends. I find the lighter pipe's smooth finish a nice "tone-down" from the rough plumbing look. All together, this kit provides plenty of strength for most furniture and the rustic pipe look, but with a nicer, lighter finish. To me that is a plus--this is a very nice kit and costs less that if you'd pieced it together from real plumbing parts (I priced it out to compare), and looks retro but cleaner. I knew what to expect because while I got this kit free on Vine, I had purchased a nearly identical kit from another seller last year.
So, I'm giving it 5 stars for what it actually is and for the price, JUST BE AWARE THE NARRATIVE IS MISLEADING. Which is unfortunate because just like some people might want the heavier pipe, I'm betting more would be attracted to the look with a cleaner, lighter feel.

Just an ABSOLUTELY PERFECT Bar Cart!
Style: Grey Oak, Size: 14.17"D x 37.01"W x 35.24"H
Completely blown away with this cart! It FAR exceeded my expectations! A little more expensive than similar items, but the reviews sold me on it! Approximately 45 minutes to assemble from unboxing. Really good instructions. Tools included. I put together lots of these Lego Projects, so I can get through pretty quickly. This is a HEAVY, STURDY, SOLID, WELL MADE piece! All of the metal and wood surfaces are smooth and clean! Its much sturdier than it looks in the ad pics. It's also a little larger than I expected, even though I did measure it all out before ordering. I had ZERO problems building this thing. It's beautiful. Lines and surfaces are my base motif, and this fits the bill perfectly! Im not a big fan of the handle but I did go ahead and install. This cart fits seemlessly in with other furniture materials and fabrics. Can be tucked neatly into a tight space, or in my case ... is anchoring its own spot under some artwork somewhat solo along a large wall. You absolutely get your money's worth with this one. An absolute score with Two Thumbs Up!

Good quality wine cart.
Very sturdy bar cart and well made. Product came well packaged, with good instructions and even some extra screws. It is helpful to have 2 people putting it together. The only downside is the wine rack will not hold fatter bottles of wine but I added a small wine rack to the top.

Very nice cart.
The cart is very functional and relatively easy to put together. I was also provided a great tip on the assembly that made it much easier.
