The product appears well built, well thought out design and functions very well! the manual stated to run for 2 hours before loading, to allow the refrigerator to get to set temperature. My experience, was that in less than 30 minutes ( I did not "time" it exactly), was that it dropped in temperature from room temp of 68°F to my setting of 38°F!
The lights that turn on, inside the unit when you open the hatch are a plus, especially when needing to get anything out of it in the dark!
It does not run for long periods of time, or very often, in my opinion, for it's size and desired use as a refrigerator that is portable! The cup holders on the lid/ hatch are also a nice feature, especially if you use it on camping trips!
Customer service from the manufacturer are excellent! The shipping company delivered it and set it on it's side. Not something that should be done with a refrigerator of any kind. I contacted through e-mail the manufacturer and they agreed with me that letting it sit upright and level for 24 hours would be appropriate to allow the refrigerant to settle before plugging it in. They also sent a followup requesting information as to if the unit had worked ok after trying the agreed action. You don't find that type of caring customer service from anyone, these days.
Very pleased with my purchase!
