TLDR Review: InSinkErator PRO750 Garbage Disposer
Verdict
We think that the InSinkErator PRO750 is a solid upgrade for homeowners who prioritize installation ease, noise reduction, and reliable performance—just watch out for some plumbing tweaks and the occasional noisier startup. Its long-term durability and quiet operation make it a good choice, especially for upstairs kitchens. However, if you're looking to process challenging waste like banana peels efficiently or want a more robust metal outer case, you might want to explore other options, potentially including a model with more abrasive waste handling capacity or a more durable build.
- Top pro:
- Solid construction with a sturdy internal mechanism despite a plastic outer case, promising durability.
- Top con:
- The rubber flange is overly restrictive, causing water backup in the sink during operation.
