This grill is an attractive piece of equipment. Overall, it seems to be easy enough to put together. On average, people reported that it took between forty-five minutes and two hours to construct. Some customers reported that it took much longer, but also said that the instruction were vague and difficult to follow. People were also pleased that the construction involved no screws, which are prone to stripping, and used only nuts and bolts, which provided a sturdier overall construction.

Another positive feature was the discreet hideaway area for the refillable propane tank, which only served to enhance the overall look of this grill.

The quality of the parts is up for debate. Some customers stated that the unit consisted of junk steel and even worse stainless steel, whereas other customers reported that the grill was constructed from high-quality parts.

Premature corrosion seems to be an issue with plenty of customers complaining about rust after only a short time of ownership. However, Weber does provide a comprehensive grill maintenance schedule, which, if adhered to, will increase the longevity of the parts.

One final complaint is that the product description states that porcelain enameled cast iron cooking racks are included, but, in actuality, customers are receiving stainless-steel racks.

Cooking with the Weber Ducane Affinity 3100

Overall, reports on cooking with this gas grill are positive. Customers have stated that the unit will produce up to 600 degrees Fahrenheit cooking temperature within ten minutes of preheating. They have also stated that the heat is distributed evenly, and produces excellent, flavorful results. Some customers also reported that the unit works very well during periods of inclement weather, but other reported that the unit was difficult to light and did not get up to temperature at these times.

Other customers have complained that the temperature control knobs do not depress fully, thereby restricting the flow of liquid propane to the burners, and that they found the unit difficult to light. Some people also reported that the push button ignition system is temperamental, and that the integrated thermometer was, at times, inaccurate.

Cleaning also provided an area for debate. Many customers said that the stainless-steel grill surfaces were difficult to clean, and the lack of a removable drip pan meant that cleaning the unit was a chore.
