Pulsar GD400BN

Arrived on time and with no shipping damage. Added included oil and it started after just a few pulls connected to propane. It runs perfectly and is reasonably quiet. It's use will be primarily a backup generator for our RV.

Super easy to work with and ran flawlessly.

Super easy setup. I ran it on propane during an electrical shutdown at my house due to construction and repairs. Flawless. Reasonably quiet, steady power as needed and not a single issue. I an considering a second unit for emergencies.

Great value

Very easy to set up and get running. I'm a 65yr old lady and it started on the 3rd pull and ran great. Hooked up to the camper and did not drag down with the a/c running. Great value!
