Rated 5.0 out of 5.0 by Rick Perfect for what I need it for.
After reading other reviews, I was hesitant about getting this but did so anyway.
Mine arrived absolutely perfect. Everything was the way it should be, I just installed the wheels and handles, removed the shipping frame and that was pretty much it.
Remember this does NOT come with oil. I added 20oz of Mobile1 10w30.
Also don't forget to attach the battery cable. I chose to buy a 40# cylinder of propane.
I installed the propane tank, just as you would a grill. Remember to turn on the propane valve and then follow the line to the unit. You will see a black canister with a knob sticking out of the top center. Push that know down a bit to purge the propane and then start it up. No need to choke or anything.
This is really quieter than expected. I like how the propane runs clean and hope I never have to run gasoline through it. No worries about propane going bad nor prepping it for storage like you would with gasoline.
I have my house wired so in case of an outage, I can just start it up, run a cable from the unit and into a plug at my electrical disconnect. That should power everything in my house as it was before. No running cables and cords all over the house.
I'd highly recommend it and would buy it again.

Rated 4.0 out of 5.0 by ccinc Does what it is intended for
The only problem we had was that one of the bags of parts broke open in shipping. The handle for the spark plug wrench somehow ended up behind the motor fan and locked the motor. I had noticed it was missing and just thought someone had forgotten to put it in. Fortunately it happened while we did the first start an it only had turned over about 3 times and hadn't started yet. I had to take the pull cord off and rock the motor backwards to free it and then try to work it down to the bottom. After doing that I needed to loosen two more cover screws to flex the cover out and let the handle fall out. Put it back together and it runs fine. I like the fact it will run on Propane and I will never put gas in it so I will never have a gumming problem.

Rated 4.0 out of 5.0 by LC55 Good Generator- Manual Needs Work
I bought this as a backup for my home electrical system. I liked the idea of having the dual power so that I didn't have to rely on one type of fuel. The generator works great, but the directions need work. For example, the white negative battery cable is not connected to the battery when shipped and the it's hard to see that it's not connected because of where the battery and wires are located, but the instructions make no mention that the cable needs to be connected. It took me a while to figure out that it wasn't because that the battery was dead that the electric start wasn't working. The directions also show a picture of a regulator that you would normally see on a gas grill. I spent some time looking for the regulator and thought that they didn't include it, until I saw that the regulator was built-in to the generator. Once you get past the deficiencies with the directions, it's a very nice machine. Starts up right away and it is relatively quiet. The electric start and wheel kit are very good features. No problem running my gas burner, water heater, frig, freezer and tv, with some lights on at the same time.

Rated 4.0 out of 5.0 by Generaly Not perfect, but a nice little fuel efficient generator. Good value, portable, convenient, and reliable (so far).
I bought this because it is dual fuel and seems to be one of the better generators in terms of run time per gallon/lb of fuel. So far I am not disappointed. Had it for going on a year now and find it is very handy. It gets used to power an electric chain saw during the summer, and is backup power for the house the rest of the time. I am wiring a transfer panel for the house in a few days, so haven't had a chance to try a full load, but don't doubt it can deliver the specified watts.
A partially half full 20# propane tank (BBQ size) has lasted for a few hours of use and still has significant fuel leftover. This fall It powered a couple of portable heaters (each on half power) during an overnight power outage. After around 10-hours of using a full 40# tank I can tell that some fuel is missing (compared to a spare full tank) but I think more than half remains.
I have mostly run on propane, but the one time I ran on gasoline the governor seemed to have trouble keeping the engine at a steady rate. With propane it runs smoothly with appropriate responses to loading, but with gasoline it seems to have a cadence alternating between racing and normal (RRRRrrrrRRRRrrrr...). It powered okay, but I suspect the voltage wasn't so steady. Since I intend gasoline only as a last resort backup fuel, this hopefully won't be a major issue. I will try again to see if it happens again. Maybe it didn't like the fuel?
Operation is a little noisy (as are most generators), but not excessively so. I plan to build a little sound barrier to park the generator behind. It is much quieter than the log splitter I used this summer, and certainly quieter than a gas lawn mower. Most of the noise comes from the engine rather than the exhaust, so a better muffler would not help much. I think some basic sound deadening material near the sides it would be enough improvement. We can hear it from the house, but mostly in the room nearest the generator. Everywhere else it was just a muffled background noise from outside.
The fold down handles would be better if a little longer and as a single loop handle. The solid tires work as advertised. It is nice not to worry about airing them up. The electric start is very nice, no pulling the rope. So far starting has been 100% reliable. Read the instructions for choking, as it is not needed for propane unless doing a warm start (even at that I don't think it is needed). Choking is necessary for gasoline.
Changing oil is mostly painless. There is room for a smallish shallow pan under the unit. The drain plug is on the side of the engine near the filler/dip stick. It drains onto the frame a little, but not all over, so a little wiping is all that will be needed. Putting an inch or two of spacer under the far tire speeds up drain time. Filling with oil requires a long funnel. There is no clock to log hours of run time, so one must be aware of run time so the mandatory 50-hour oil change can take place on schedule. I think it is good with any kind of 10-40 automotive oil. I am using Castrol synthetic blend. Also, these things burn a bit of oil, so be sure to check it every 10-hours or so.

Came complete with all parts and was easy to put together. Fired up on first try on unleaded and ran for a hour with small load. Then tested on propane with no issue. Just recently lost power for 30hrs or so ran it for about 15hrs powering fridge, freezer, tv and a few lights with no issues. Went through one BBQ tank cylinder. Happy with purchase and would buy again.

Rated 5.0 out of 5.0 by Lucky Great little generator IF you get one unbroken!
Great little generator. Easy to assemble (because I had to do it twice). Runs great on propane. Easy start. Only drawback is that either the shippers or warehouse must have been playing football with these things. First one I got had a broken motor mount and a crushed air cleaner. I returned it to my local Home Depot with no problem. Called customer service and they were great! Sent another one out within a week at a 10% discount. Put it together today and the frame is bent up. I straightened it out as best I could and it sets level and runs great, so I am keeping it. I don't ever plan on using gasoline except in emergency so it should last for years!

Rated 5.0 out of 5.0 by JimW Dual Fuel Option
I needed a generator that had the ability to run longer than 8 hours on a tank of fuel and to not have that fuel degrade the carburetor, or in the tank. I chose this unit because it could run for 8 hours if necessary on gasoline, or 2 1/2days on 100# of propane. The low oil shutdown protects the engine. It assembled and started readily, but it awaits the big test.

Rated 5.0 out of 5.0 Good Buy
I owned a Duromax Generator model 5500w running 6500w surge for over six years before it was flooded by hurricane Sandy. When came time to buy a replacement it turned out that Maxtools do not make 5500w model any longer. I had to opt for 3500w because it was more manageable weightwise than its counterpart 8000w unit. I have to say that new unit is way quieter than the one I had before. After much consideration to buy more popular brands the main reason I bought Duromax generator again was that it has never EVER failed to start. It had always started on the first cranked. No drama.
