I have had the rectangular kind of chafing dishes before, and they tend to dent. True, they hold a bit more food, but they don’t look as nice and I have had two different sets that got dented. These round ones are beautiful looking and stronger. They are perfect for weddings or other nice occasions. They’re even great for a backyard function - everyone will be impressed and have warm food.
They are easy to use, but do you require putting them together first. Don’t wait until the day of your event. Get it done early so you’re not stressed out. They’re not difficult to bolt together, it just takes a little bit to assemble all four of them. I am very happy with mine and highly recommend them.
