Product review (4 stars): ... using ours for 3 months and the temperature sits nicely at 40 on the #4 setting
We have been using ours for 3 months and the temperature sits nicely at 40 on the #4 setting. I choose not to put it on a lower setting, but I'm sure it would get colder if I did. Its a bit noisy when it comes on but it doesn't come on super often and its only a bit more noisy that our fridge ice maker, so I don't have a problem with the noise.
