I will start with the best first as they out weigh the few complaints I have. The generator came in perfect condition (more a credit to the shipping then the manufacturer) right out of the box all you need to do is add oil, attach the battery, and add a fuel source. The oil in included in the shipping box.I hooded it up to propane with the included attachment for propane tanks. Very easy and most of all what I like is no mess with gasoline. On the subject of gasoline, a nice feature I like is the rubber protector spill mat around the gasoline fill area. (see attached photo) It snaps into place with molded inserts for ease of removal for cleaning if you do spill any gasoline. It will also protect the plastic from discoloration or damaged from accidental spills.After hooking up the battery, propane and filling the oil it started quickly and ran perfectly. I followed the instructions for proper break-in operation 10 hours with minimal load. I ran a battery charger.Over all I could hardly be any happier with this unit. It is very quiet runs everything smoth and fuel usage is low. I haven't done a scientific test on fuel usage yet because I am not able to at this time. But I can attest that if under a constant load and under 50% it is better then I had expected, I can roughly say 12 to 15 hours run time on 20lb propane tank seems to be accurate.I like the remote start as long as you have a way to keep the battery charging when the generator is not in use. If you are using for an RV be warned. You have to have the switch for power turned on in order for the remote start to function. This will drain the battery if left on for an extended period like over night. So if you wake up in the morning to brew coffee the remote start may not work and neither will the electric start, You will have to use the pull start. This issue can be bypassed if you plug in to a inverter on battery backup to maintain the battery on the generator. Just a small issue.The wheels are better than I expected being made with a foam core not just hard plastic, and the roles over ¾in gravel with only a little dragging. Though I don't think it could go over much more without issues.I very much like the extending handle and over all moving it around on the ground is a breeze. Now as far as lifting it's still a 100lb unit and even for myself being in great physical condition, I wouldn't want to lift is alone anymore then I had to. It's just the overall size is not easy to move by oneself.Now my complaints. #1 Oil filling and draining. We all know the best way to care for a machine is to change the oil often. You really can't over charge it. With that in mind it's baffling the designers never seem to think about making this an easy and clean task..I have now doubt I will have to make some motivation so the oil will actually run out the hole in the bottom plastic housing tray. Same for filling the oil. One has to use the included funnel and I do thank them for making and including that. But is is hardly down hill to get the oil to run into the engine. Even after the task is completed, you will be left with an oily funnel to try to store some place it will stay clean until next oil change. Again I would have liked to see more though go into both this and the draining. Best advice I can give is have shop towels under neath, ready to catch the inevitable spilled oil.#2 Security!! the unfortunate truth is unless you have inside your garage, where it can't be used. Or inside something else aka a van, (where it also can't be used), there is no good way to secure the generator. For most people this would seem to be a major issue, whether it's in the back of a pickup or on a reserver hitch cargo area like I use it, There needs to be a better way to secure the unit. I am disappointed that such a major oversight exists on an item like this. I would have expected dedicated bolt down points for permanent mounting. You definitely can run a chain through the handles if you don't mind the rash and other damage bound to happen and I am not confident this would be a great solution. If you're like me and injoy you stuff to look nice, the thought of chains scuffing the outer plastic of your brand new 1000 dollar perches then you will have to get more creative. There are 4 studs on the bottom with coupler nuts can be a anchor point, that are sturdy enough. (moter mounts) but you will have to be the one to figure out how to turn that into a fastener point because the designers didn't. I find that a big mark down but I haven't seen this fixed on any other units so it's not like we have a better option.#3 high altitude. I am disappointed the generator doesn't come with the parts for it to run correctly at altitude. It wouldn't be anything big for them to just include the correct jet for the carburetor. The added hassle to have to track down the needed parts, added expense is just a pain. so if your using over 2000ft be prepared, plan ahead and get your parts ordered.#4 I only have about 20 hours on my gen. So ATM 08/15/22 I can't speak to the reliable but I will update this review with any relevant information.Overall I recommend this generator inverter over others I have experience with in the same price range. It's not perfect but I think there's some good value added with the included propane hook up equipment and nice extras like the way the wheels and retractable suit handle work.
