Horsepower matters: 1/3 HP is weak and jams easily; 3/4 HP or 1 HP grinds faster and lasts longer. Look for stainless steel grinding components to prevent rust. Available from $349.
Disposals use almost zero electricity since they only run for seconds a day. There are no consumables, making them a very low-cost appliance long-term.
Common Failure Modes
Jamming from fibrous foods or bones is common but easily fixed with a hex wrench. Fatal failures usually involve internal seals breaking, causing water to leak into the motor.
