Product review (4 stars): Decent thermometer for the money
I bought two of these - on for the fridge and one for the freezer of my RV.  Because I bought two of them, I was able to test them for accuracy.  One or both of them is wrong, as when they are placed side by side in the same compartment, they ought to be virtually identical.  Instead, they were about two degrees apart.  That means that one or both of them is inaccurate.

Still, for the money, I would consider these to be "good enough."  Even if I assume they are off by 2 or 3 degrees, they are suitable for my RV.  The hang on the refrigerator shelves and manage to stay attached while I'm towing the RV.
