Excellent experience July 6, 2018
Reviewer: Anonymous Person from CHELSEA, MI United States  
The generator arrived on the promised date and started right up (after adding the oil of course.) I would definitely order from this company again.

Yamaha EF1000iS review August 31, 2017
Reviewer: bob Griffith from Seattle, WA United States  
I am very disappointed by the noise level of this gen., it is much louder than my Honda 2000. The exhaust is much too loud and it has a loud irritating whine. I also noted that the armature is exposed which concerns me because we use our gen a lot in the rain. I am thinking of  changing to a Honda. Can you trade?
