little larger and heavier than expected, but nothing that can't be dealt with, temperature only reads in celcious (spelling?) it has dropped from 25 c (78f) to 0c (32f) in 15 minutes, there is no air circulation so it would take a while to cool items from ambient temp, to 35-40 f, It would be fine to add 1 or 2 warm items in with colder items, it is intended to maintain cool temperatures rather than a cooler full of warm items to cold, I suggest printing a c-f conversion chart or just remember 0 celcius is 32 farenheit, it has now cooled down to -1 c in less than 30 min. I may try putting a small computer case fan inside to speed cooling, but as it is, it does exactly what it is supposed to, and does it well
