Rated 4 out of 5 by from very good the one problem I have had is for the parts that need to be added to the generator including a battery (which I think should be included so you dont have to go find that after purchasing) and oil fliters. There should be a guide or follow up link on how to order these parts.

Rated 5 out of 5 by from We love everything about it. We like the generator so far. We have had it less than a week but are very pleased with the entire product. The noise is minimal, and it is not bad to look at either. We lost electricity the second day it was in and it kicked right in and did its job.

Rated 5 out of 5 by from 38kW Brian Stuller and his crew performed like a well run machine. Did the job perfectly, on time, cleaned up, exactly per the contract. I could not have asked for a better contractor.

Rated 4 out of 5 by from The Lights are Always On We installed our first Generac unit (smaller 20kw) at our in-town home. Though we only lived there for about 2 years we did loose power several times and always welcomed the sound of that Generac firing up. We moved back to our larger home and purchased a much bigger unit (38kw) and since installing it 4 months ago, have lost power at least 6-8 times. This unit (water cooled) is as quiet as a car running. We watch the block go dark as we continue with AC, TV, Lights and all the conveniences of power. The APP on my phone alerts me every time the unit does it's tests, and I look forward to every Friday @ 9 am to those text alerts. Our dealer is GREAT - and provides excellent service. We've recommended them to our friends and neighbors.

Rated 5 out of 5 by from Generac Generator My new Generac Generator has given me total peace of mind from ice and wjindstorm outages. It has already swung into action on 3 different outage issues in the first 6 months. I can leave home now and not worry about a power outage and the safety it brings to my livestock. It is very quiet and I don't even know when it runs and it is located close to my office in my house. I am totally satisfied with my purchase.

Rated 5 out of 5 by from Outage response Thankfully, we have only had one short outage since installation. A transformer switch blew and I counted to 20 and viola the lights were on. About an hour later power returned and generator went back on guard duty. This happened during the night and my wife never new it happened. One of those things you buy and hope you never need it ( primarily for your neighbors) but darn glad you have it if needed
