We've used InSinkErator for about 13 years now, three units total. Two were replaced for free after developing problems, an easy no-hassle task with great cooperation from Customer Service.

Pretty much trouble-free installation. A couple minor "improvements" would help installation. Slightly longer (maybe 2 inches) tubes would make location of the unit and hookup easier. Including standard copper tube compression-fitting hardware woiuld be a convenience also.

Overall, a well-designed product that we like to use daily.
