Yamaha EF12000DE Generator May 27, 2013
Reviewer: Anonymous Person from Lake City, MN United States  
Great price with free shipping. Delivered in one week. Shipper was very helpful- took 400lb item off truck and even put in garage for my wife. Have called them to ask questions regarding battery for the generator, they were very pleasant and helpful. Very satisfied customer.
