Product review (5 stars): you really need a product like this for Dometic fridge in RV
using daily.  you really need a product like this for Dometic fridge in RV, as when operating while parked the temp varies so and you need to know that your fridge is working at optimum temp for food preservation.  we also bought the fridge exhaust fan on Amazon, and it helped bring the temp inside the fridge 7 to 10 degrees - which we know because we bought this thermometer.  very satisfied with both products.
