The acurite is hard to beat. If you use a 'wired' unit, then even a thin wire through the freezer/fridge gasket can cause problems. Be sure ANY battery type unit (like the acurite) that goes in the FREEZER has lithium batteries NOT alkaline, normal, or rechargeable. The lithium are not affected by the below freezing temps as are the others and will last longer.
I am a weather reporter for a local TV station. Living in Northern MN, I am familiar with how batteries handle low temps. Alkaline batteries are OK until -21.9 deg. At that temp they freeze. Lithium are good to -39. I was cautioned by Lacross, who make many wx stations including mine, not to use lithium batteries in the main display unit as they are not compatible with the electronics.
Bottom line: use alkaline batteries for refer and freezer applications.
