I have used cool boxes similar to this for many years. I drive a lot of miles in a van and like to keep drinks etc cool on the journey.
This cool box knocks the others into a cocked hat. It is brilliant!
Even on the hottest days it keeps things very cold.
Controls are sinple and the temperature is adjustable from chilled to VERY COLD. I'm pretty sure that with a cold/cool ambient it would freeze items if set at full.
I haven't tried it on the warming phase but am sure it would be just as good.
Extremely well made but a little noisy. Doesn't matter in the van but could annoyif camping.
It is a little dearer than others but, in my experiance, well worth the extra money because it works so well.
