I bought this to brew ten gallon batches of beer and believe it is very good quality for the price. The temp gauge was accurate and the ball valves worked as they should and did not leak. Installing the hardware was easy when following the included instructions. They even provide plumbers tape.

The pot is very durable... Mine came ever so slightly out of round (enough for me to notice and bother me but not smashed or damaged by any means) and it is very hard to try and bend it back. The steel used to make this item appears to be good quality. The handles are sturdy and welded on. Not as good of quality of welds as higher priced items but very good for this price point.

My propane burner got soot all over it on the outside and the wort on the inside left a sticky mess when I was finished brewing. Both came off with no problem except the very bottom on the outside which was exposed to direct flame and had some remaining black char which I expected.

Overall I'm very happy with this pot and will likely buy two more eventually to finish my Brew system. I definitely recommend it for anyone wanting to Brew ten gallon batches of homebrew beer.

I use this for cheese making. Also yogurt culturing and straining. Very nice pan

The Good:
My kettle showed up well packaged with bubble wrap and dent free. All the parts were there. It was exactly as pictured.
This is a high quality pot. Heavy gauge and the handles are firmly riveted in place. The lid fits well and has a handle which is welded on nicely. The kettle really shines. It has "60 QT" etched on the side. The top edge of the kettle is rolled as is the edge of the cover making a nice smooth surface. Adds some rigidity as well. The lid hangs nicely from the handles. They are obviously made for this function. The holes are nicely finished no burrs or rough spots. I compared the thermometer to my glass stick thermometer. It was spot on out of the box. I have one of the same thermometers for my mash tun. That one came about four degrees off but they both have an adjuster on the back for calibration

Observation:
The kettle holds 16 gallons to the edge. 15 gallons leaves 1.25" to spare.
Edit: I carefully measured the volume this weekend so I could etch volume markers. The kettle holds 15 gallons exactly to the edge. I must have had too many home brews the first time.

The drain hole height will leave a gallon of liquid in the bottom of the kettle.
It takes 6 gallons to cover the thermometer probe. That's O.K with me since I will be using it to measure the temperature of strike water and hot liquor.
The Thermometer probe sticks 2.75 inches inside the kettle. I suppose this would accommodate the addition of a sight gauge however, it may be annoying to those doing brew in a bag. My other thermometer has a shorter probe. Although I don't do brew in a bag I may swap it out if it becomes annoying when stirring or using my wort chiller.

The Not perfect (but still OK):
The instructions say to wrap around nine wraps of supplied Teflon tape around the coupler threads before inserting the couplers through the holes in the kettle. I found that the tolerance of the holes to the coupler made it nearly impossible to get the coupler through the hole without damaging the tape. I struggled a couple of times and still had a leak. I solved the problem by applying my aquarium hobby experience with bulkheads. A PVC bulkhead has a flat flange for the gasket to sit against. The flange is part of the coupler assembly and serves the same function as the outside washer supplied by Concord. The problem with the washer is that it is NOT sealed to the coupler so leaks can develop around the inside of the washer. The solution is to use a little bead of RTV silicon to stick the outside face of the washer to the coupler. This sealed it up nicely without all of that tape and I will be able to disassemble it without struggling to get it back together without leaks. Solder might work for those that are handy.

It goes (from the outside) coupler > silicon bead > washer > outside seal > kettle wall > inside seal > washer > nut

There are no graduation inside the kettle. I solved this by making a stick with graduations. The graduations are 1.25" apart.

Summary:
This is a very nice and economical kettle. I would recommend it to anyone wanting to make beer or do a clam bake for 20 people. I would definitely buy it again. I would have given five stars but for the lack of graduations and the thread tape method of assembly.

Update: As indicated above the pot holds 15 gallons to the edge. I have had 4 brew days witht this kettle and I am quite happy with it. The bottom has stayed flat too which is something I was worried about

Its beautiful. It was well packaged and arrived without any noticeable defects. The instructions it came with were clear and simple to follow. Once I assembled the kettle and its parts. I filled it to the rim with water for 5 hours to test for leaks. It did not leak. The ball valve was sealed. The thermometer was sealed. The rivets where the handles are riveted were sealed as well with no leaks. Additionally, the top rivets is approximately the 9 gallon mark. My thermometer read accurately, I used two additional thermometers (one digital and one manual) to confirm reading. It also has a calibration screw on the back of it, if it needs adjustments. I will use it this weekend to brew an all grain beer recipe. I'll update if there are any changes.

Nice product for what it is. The size is not accurate. 120 quarts (30 gallons) size is 28 gallons over flowing. Only usable to 25 gallons.
