From FIRMAN Power Equipment
Good generator works. Great, but is a lot louder than they say.

Would Not RecommendWorked 3 times, then stopped. Firman will make you run around and troubleshoot the issues yourself and give you contradictory instructions. Eventually they will have you take it to a service center where you will find out they have stacks of this same model all which don't work. Firman wont do anything about to offer a soluation like a return authorization to Lowe's, if you purchase the extended warranty through Lowe's, they will tell you to go through Firman instead. $800 Paperweight, that I ...

Garbage- do not buy from Lowe’s.
Would Not RecommendWon’t hold the load it is designed to hold. Don’t buy from Lowe’s because they don’t honor the 48 hour rule.

Advertises saying runs for 12hrs I got 8hrs
Would RecommendWorks great! Only thing is it advertises as running for 12hrs on a full tank that’s false it only ran for about 8hrs till it shutoff with no gas. Other than that it’s great!

Best generator ever purchased
Would RecommendI have had this generator since early 2024 and it has logged hundreds of hours on our off-grid property. I use only high octane fuel and watch the oil level closely. The push button start is so nice. What a great generator!

Runs great, quiet and plenty of power
Would RecommendFits needs of my RV. Easy start both with electric or pull rope. Runs 15-20 hours a day as I replace propane/electric fridge with a domestic model. Would have given 5 stars. Disapointment comes, as with most everything, .fom the stupid operational design. Firman wants oil checked daily and changed @ every 100 hours. Now go find a phillips head to remove the cover. Why not an easier twist lock 1/4 turn finger lock. While your at it put some teats on the bottom of the access panel so it doesn't s...

Very good but louder than the competition.
Would RecommendI have been full time rving for about 2 years now. 35’ travel trailer with a huge Coleman Mach a/c on top. This generator runs the ac plus the converter, 120v fridge ect all at the same time. The bad reviews seem like a fluke. I just checked i have 750 hours on this unit! I do my maint but not anywhere near what the unit calls for. Its deff robust. My only reason for 4 stars is its not as quiet as it could be. Compared to a eaither of the red units its like a construction site. Not possible t...
So far so good
Would RecommendUsed this product once so far. The dual fuel is nice. I plan to use propane when possible so I don’t have to worry about fuel line issues in winter. The wheels are a nice touch to move long distances. At almost 100 pounds it can be loaded by 1 person although 2 is better. The included accessories such as extension cord and cover are nice
