I bought this after my 18-year-old Insinkerator stopped working because the on-off mechanism had worn out. The company gave me 50% off a new one, which I received promptly, and my plumber had no trouble installing it. He wasn't familiar with this type of disposal and was impressed with how it worked. The new one has a magnetic rather than mechanical switch, so I expect it to last for a long time. I've owned Insinkerators for over 45 years, and this is only my third one, so they're definitely long-lasting and worth the money.
