After years of use in a Davoline 4503 stove, where the burners were almost dissolved, I replaced all 3 of them based on their codes (this is the middle burner) and it's like new again. It takes a little while for the factory material to burn and stop smoking to get rid of the smell during the first ignition, which is completely normal. It heats up very quickly and maintains a high temperature. No comparison to the old burners that had understandably lost their performance. For now, after almost 5 months of relatively moderate use, I am completely satisfied. The reliability will be proven over time.
