Users say:
Customers have had mixed experiences with the AO Smith water heater, with some reporting that it failed within a few months and others having to replace it. The product is easy to install and has a 12-year warranty, but some customers have experienced a weird low humming sound that may be a coincidence. Additionally, some customers have had to replace the burner after only a year.
