Fire Hazard

Good little generator for the price and power. during break-in, which I couldn't find information for in the manual, I noticed my grass was scorched. The muffler points down to the ground. This is absolutely a fire hazard. I have 5 other generators and none of them do this. they vent up way off the ground. This points right at the ground. 100% unsafe.

NOT SUPER QUIET

I bought this to use at softball tournaments to run fans. It has all the bells and whistles, but the “super quiet” bit is what sold me. I just started this thing up to do the 5 hour burn, and it is just as loud as my big generator that will run my whole house. Do I have a defective unit? The 1 star is for packaging. The packaging is solid.

Poor Manufacturer Customer Service

Generator was missing parts upon delivery. Genmax customer service was substantially lacking in both polite interaction and accommodation. Ultimately, I elected to have the entire generator exchanged through Sam's online and the original generator picked up for return. I can't imagine that this option was a cost benefit to either company (neither Sam's nor Genmax--and it's reputation). For those wondering, I never actually fired up the generator, so I am unable to speak to the effectiveness/functionality of the generator itself--apologies. The moment you add fuel/oil to a unit, Sam's and their delivery services get difficult about accepting (or how they accept) the returns, thereafter. I do give Sam's 5-stars for zero grief on processing the exchange--Thank You!
