Just got it yesterday 9-8-2020. Added the oil , hooked up battery and it didn’t even take 5 seconds to start and it is so smooth, I have a smaller general iq 2000 which is very quiet I don’t have a decibel meter but I can’t tell the noise difference and the Westinghouse is more than twice the power, awesome.
This generator is super quiet. I was not expecting a 4500 to be as quiet as my previous 2000 from another manufacturer but it is. Remote start and push button start are great features as well. I am very happy with my purchase and would definitely purchase again!
