This planter is really tall. Ok, when I look at measurements online, I kind of get a gist in my head of what to expect. I sort of miss-gisted – this thing is really tall – like I was contemplating putting a top on it for a table kind of tall. I measured it, it is 30 inches tall – almost counter height. I usually assemble things like this inside my living room as it is carpeted and warm – when I finished this one, I had a moment of panic, realizing I had to get it through the door to get it outside. Luckily, it will fit as our front door is 36" wide, but for a moment, my brain thought, "Oh crap!"
It is also very well made – the panels are thick, and coated with a very durable, rugged paint. It is really nice, high quality and durable.
Assembly isn't as bad as you'd think, either. I have put a lot of these things together, and this one came with bolts that have wing nuts instead of what I'm used to – just nuts and bolts. The wing nuts made the assembly much easier than usual, but the extra height made it tricky – I ended up enlisting my husband to help – he was on the inside and I was on the outside. I am sure I could have put it together on my own, but it would have been tricky because my arms are not that long, so probably would have taken a lot longer – I recommend having a second human helping.
It comes with gloves and a screwdriver that is needed to get the bolts tightened down. Overall it was a lot easier to assemble than I expected once I'd seen the size of each panel. I've included a few pictures of my husband playing hide and seek with our dog using the raised bed as a hiding spot. Hope this is helpful.

The galvanized raised garden bed weighs 28 pounds and 8.4 ounces.  The total assembly time was 44 minutes and 26 seconds.  
The bed consists of 6 ribbed metal panels that are painted a glossy brown. One panel is 30.3125  inches tall and the circumference is 19.125 inches.   
It was simple to assemble.  Since it is freezing outside, I assembled most of it inside.  I took three of the panels and attached them with the included screws and wingnuts. It took 14 minutes and 9 seconds.  A small Phillips screwdriver and gloves are also included.   I did not use the gloves at all. The panels are not sharp or jagged. They are painted and manufactured well. All the holes lined up perfectly.  I am 5'7" and I could not put the bottom screw in while still being able to put the wingnut on. Therefore, I flipped it upside down.  When the 2 sections of 3 panels were put together it was 27 minutes and 28 seconds.  I carried the two sections outside (not included  in the assembly time) and connected them. To install and tighten the bottom last two screws on each side I tipped it on its side.  The bed is very sturdy. I had zero issue lifting it in its cylinder state and carrying it into place, so it is ready for spring. 
There are 10 screws and nuts that are used in one column in the assembly for a total of 60 used.  Five extra screws and six extra wingnuts were left over which is an advantage.   The circle is 34.75 inches in diameter at the top exterior and 35.5 inches in diameter at the top interior.  
At those dimensions filled to the top the amount of dirt needed is 28336.74 cubic inches or 16.4 cubic feet or 0.61 cubic yards.  
I plan on putting turnips and rutabaga [B0C21Y8CDL] in the garden bed by starting the seeds in a seed tray [B0F2187FZ9].

I am absolutely thrilled with this Galvanized Garden Planter . It's a truly great value for the price and the quality exceeded my expectations, featuring a very sturdy and durable material that feels high quality and built to last outdoors. Aesthetically, the planter is really nice and beautiful, with an attractive sheen on the metal in the lovely Café Bronze color, making it a gorgeous addition to my space. While it does come in a few pieces, assembly is super easy and straightforward all the necessary bolts are included, and they even provide a pair of gloves to wear while handling the pieces, which was a thoughtful touch. There is a little bit of work putting it together, but the end result is a really sturdy and impressive planter. Overall, I absolutely love this planter, and it's a fantastic investment for any gardener!

It was much bigger than I anticipated. Stronger and higher quality as well.
The raised planter was too big to get outside so I had to remove a panel and then reassemble. Im still working on yard placement and what to plant in there but I do plan on doing a Hugelkultur where Im putting in a few oak logs, cardboard, and lawn clippings. Followed by a decent soil mixed with perlite. Im thinking of doing some hot peppers in this vessel. Its large enough to put a single high yield ghost pepper or the like.
Assembly was straight forward. I used my power drill instead of the included screwdriver. Took about 15 min..
It is thick metal with a nice paint job and zero sharp edges. It came with extra hardware as well.

This review is for A ANLEOLIFE 30" Extra Tall Galvanized Raised Garden Beds Outdoor, 3×2.5ft Round Metal Planter Boxes for Planting Vegetables, Flowers, Fruits, Eco-Safe & Easy Setup, CaféBronze
Pros: Corrugated steel panels of a suitable gauge and alloy to last. Powder coat finish is durable and well done. Assembly is simple, hardware is sufficient, and the final product is great. The extra tall height makes it easy to tend to the garden without strain. This will be my go to bed for longer root crops like specialty carrots and burdock.
Cons: I wish stainless steel, titanium, brass alloy, or some similar corrosion resistant metal was used for the connecting hardware.
In total, this is a quality raised bed, I would definitely get more.
