Wonderful purchase. Was very skeptical purchasing online but the price was very good. My husband said it is worth every penny. Generac is a reputable brand. It fires up quickly and never has a problem. Highly recommend.

### ⭐⭐⭐⭐⭐ A better piece of equipment

This is a much better piece of equipment than the ‘mass import’ companies offer. Smoother operation with negligible metal to metal noise. Much tighter operation. Just a better piece of equipment
