@yanathem @Emma Hughes Thanks for the replies. I traditional JFDI style I ordered it anyway and it arrived earlier. I'd heard of Indel before but until i saw your posts hadn't known about this particular model.
I definately won't stand on it
It cooled from 23c to 0c in approx 10 mins on the mains (It needs a transformer for mains use rather than 12v). It's (very) occasionally powering on to manage the temperature.
For the overall size / external dimensions the internal volume is really impressive - 18l vs 10.5l in the equivalent Dometic (that can fit between the seats)
The Danfoss / Semco compressor is super quiet. We were just comparing it to the now defunc't (and broken) Aldi electric cooler we'd been using.
I paid £288 for the fridge + £26.99 for a transformer.
