It is reasonably quiet and fairly low vibration. Looks well made and sturdy. We are pleased with it so far, time will tell how reliable it is. We intend it to power small tools in our new workshop/shed, also for paint spraying. These jobs were previously done by a larger / heavier 3 HP single cylinder machine in a larger workshop, prior to lock-down. That machine eventually failed, due to being housed outside and not being properly maintained. This one will not be abused in the same way, as it is ours to look after.
