Amazing generator
My friend purchased one of these several years ago and I had to have one. It’s so quiet it doesn’t affect anyone at our campsite when camping. Starts fist try every time. It’s a work horse for sure!

Super fast shipping
Love this unit, the handle the lite 98 lbs is very manageable. The remote start is a great feature also. It’s very quiet. I now have owned this since Dec. this unit has ran every night when temps drop below 20 degrees. With temps 15 below zero on many nights this started and ran flawless.aThis has been a job saver for me, I can't say enough.

Perfect Generator
I purchased this to use with my toy hauler camper and it's worked great, very quiet allows me to use everything within the toy hauler without a hitch I haven't had any issues with it. A few of my family members have purchased the same one for themselves also to use with a camper or living quarter horse trailer and they also haven't had any issue with it at all. I love the remote start and shut off key fob it works for a good distance.

Powerful generator, great for RV owners.
Love this thing, travels in the bed of my truck, the remote start is an awesome feature. Plugged into my camper overnight no need to go outside to start on a cold wet morning. Great product. Would highly recommend to other RV owners.

Quite upset
I bought this generator and it never worked from the time I took it out of the box. Of course I can't send it back because it's had fuel and oil in it. So I was told to take it to my nearest Cummins dealer which is 50+ miles away, which is where it has been for the last almost 4 weeks. Sitting with 0hrs and now I'm being told we're waiting on warranty for an answer on what their going to do. That being said I paid $1200 for a paperweight I have never been able to use.

This thing is a win for sure
This thing is a champion generator! We were without power for a week and it really saved us. The remote car starter is super dope. People are always jealous of how quiet it runs. It’s definitely, definitely worth the mulah!

Seems to be a good quality generator so far.
The product was delivered on time, but the battery compartment door waa dislodged during shipping and ended to inside of the generator. This was most likely due to the battery not being hooked down, as the battery was also loose in the box. So far the generator has started and ran for about 1 hour. It was easy to setup and get going. It runs very smooth and quiet. I would recommend generator. No complaints so far.
