Excellent generator for a very good price!
This is a excellent generator that can handle most applications and it’s relatively simple to use fairly low noise levels

Serious manufacture equipment defects and warranty process experience terrible so far
Does not meet expectation, serious manufacture equipment defects and warranty process experience terrible so far. Fuel tank collapsed under vacuum after equipment ran for 6hrs. There is no adjustable feature to control fuel tank ventilation meaning this issue can only be caused by manufacture equipment defects.

We have not yet used the product. The only thing that is bothering me about it, is the weight 430 pounds. It’s hard to believe that that could be portable unless you’re young and strong.
