Question: can it be used in a 220V country? or is it just restricted to 110v? thanks!
Document: I have used InSinkErator disposals in every home I have ever owned. The speed and ease of installing makes this my first choice. I have never heard a more quiet running disposal. I just replaced a ISE which served me over 14 years without problem till now. Amazon got me this product in a very short time and at the same cost as the one I replaced. Thanks Amazon. I would recommend this product to everyone.
It is really quiet and I like it so far and I don't know how long is the warranty of it. I heard it 8 yrs but I was too busy to read the warranty. So far so good.Thanks.
Much better than any that I have ever used. This is a top  shelf disposal.
Amazing! Powerful but so quiet you can barely hear it! My old one used to rattle the dishes in the cabinet.
purchased this disposal for our kitchen remodel. When I turned in on for the first time, I wasn't sure if it was actually running it was so quiet. Used it a couple times and seems to do the job quickly.
The electric cord is not supplied so he used the one from the old (3-year) disposer. You may have to get a cord if you're not hard wiring the disposer. After one week of intense use, I think it's great.
Just like clock work. Ordered this disposal, it arrived in four days and was installed with one tool and a flashlight in 40 minutes. Literally cost one-third of what buying one in town and having a plumber install. Hooray Amazon.com and thanks to customer service at In-sink-erator for recommending this model to replace our old one. Really, really quiet, too.
Replaced a Badger 1/3 hp unit with this. It's like night and day. Just as simple to install, but the similarity ends there. Much quieter and no vibration at all, except with the toughest load. Old unit used to shake the pipes apart, but this one is great.
I liked these food disposals so much that I bought two of them. Having used mine for over a year, I can say it's the best garbage disposer I've used. It's strong but quiet. So much that I can turn it on with a sleeping baby and not wake him. You pay a premium, but its worth the money.
I bought this disposer a month ago, and so far i love it, it even works with chicken bones. and its very very quiet, I have a small child and he used to get scared with the huge noise of my previous disposer, but with this one he does not care at all. Im not an expert in disposer but this one is a way wider than the old one, so be ready to cut some pipes if you plan to install it by yourself.
