Generac GP3500iO Review

PROS

Compact and Ergonomic Design

Its Really Quiet

Easy to start. All it needed was to turn the dial from Off to Choke or Run, make sure the gas cap vent was turned to On, and Eco Mode was turned to Off. The starter cord was easy to pull, and the machine usually started on the first or second pull.

Runs for a very long time.

CONS

It has no wheels.

The Generator is a little too heavy
