Mine stays between 37* and 38*, but if you stay between 34* and 40*, you should be good.
Got another questions I saw you post "Put each Eye Round in it's own individual Zip-Lock bag & put in fridge at 37˚/38˚ for about 10 days.". So because I have two kids in and out of the fridge all day I have noticed my fridge swings from 38-42 throughout the day. So it tried a thermometer in a glass of water to see what something with some mass reads and I have found the water is hitting 39 all day today but will check in the AM to see what is does over night. So just as long as my water does not go below 36 am I ok?
