I have used Acurites in all my freezers, both at home and in the RV's, for a number of years. Never had a problem with them not working. I do, however, change out the batteries every year.

I want to read the fridge and freezer temperatures without opening the fridge and freezer doors.
Gotcha, mine work great for that. And the batteries have been used off and on for about 3 years. I'm very happy with the battery life. I'll do some checking and see if I can find the name.
