I had an Aspenora.. the latch fell apart on day 1, by day 3 the hinge carrying the wires broke. The Amazon Seller offered to ship another or refund 50%.... obviously admitting the unit was faulty. I said no, I wanted a full refund, I had the original packaging and if they sent a label I'd ship it.... no reply... a week later I contacted Amazon, they sent me a full refund, no questions.
Aspenora is garbage.
Next up was Joy Tutus. Performance is good. Lots of washboard roads with no issues. The only complaint is the latch is a very weak magnetic seal and you MUST tie it down. Not really an issue since I run a strap over it on the road anyway but ....
So far I've been low budget but I'm starting to believe "you get what you pay for".... If I need another it will be a brand name like ARB or Dometic or Norcold.....
The tough thing about ordering on line is you have no idea what you will get until it is paid for.
Amazon is great if you have issues.
Mine runs on pure solar, 2, 100W panels to an old car battery. I ran it all summer with beer and on 3, week long road trips. Flawless and simple. The Renogy charge controller cuts in at 11.4V and out at 14.4V. Overnight there is a 0.5V drop. I am now looking at a 2000W Inverter, electric kettle, induction single burner and microwave, all under 1500W. I figure I will need a bigger battery but I am sold on a pure solar setup. No propane, no tie into the vehicles electric system. And zero operating costs.
I travel alone, I cook for me only and I hate cooking so the simpler the better.
I see the solar starts charging at first light, long before sunrise and it charges well past sunset too. Even rainy, overcast days have little effect. My cooler stays cold all the time.
