Great Refrigerator/Freezer Thermometer
By Stanley Wu Jr.
Recently purchased a side-by-side refrigerator/freezer and was curious
as to the temperature in each compartment. Moistened the suction cup
per instructions and affixed it to the freezer door's interior, set at
the recommended mid-range temperature. Checked the temp the next morning and it registered 17 degrees fahrenheit. Had to take a plastic knife to
pry the suction cup off of interior freezer door. I next placed this
thermometer inside the refrigerator door, about chest level above the one-
gallon storage shelf for easy viewing. Again with refrigerator temp set at the recommended mid-range temperature, I returned to check on the temp the following morning and it registered from 38.7 to 41.5 degrees fahrenheit depending on late night door openings. Periodically repeated this phase of refrigerator testing for a month to confirm the absence of
sporadic readings. No problem with the suction cup dislodging from the
interior refrigerated surfaces. Great buy for the low cost ..... all is
needed is to replace the button cell lithium battery and you can regularly monitor the cooling capability of your refrigerator/freezer and additionally give you an early warning sign of when you need to purchase a newer, more reliable appliance.

Not bad, not great
By Randall Nortman
My two main gripes are that (1) the suction cup tends to work rather poorly at cold temperatures, which is something you'd think they would have considered for this particular device, and (2) that it can be very hard to read the digits at an angle or in the refrigerator lighting, and if you remove it to read it, it will quickly fog up and also start heating almost immediately, resulting in an inaccurate reading. The second point is really mostly a nitpick, as it would be hard to fix this without going to a more expensive backlit LCD display, but the first point is a fundamental flaw.

Cheap and slow thermometer
By Physical Engineer
This is a cheaply designed thermometer, the LCD screen is see-through, but the background screen color is nearly the same shade of grey as the letters making it difficult to read against a dark background. It takes a reading every 2.5 minutes, and it took 20 minutes to register a change of 3 degrees. The accuracy seems to be +/- 0.5 - 1.0 degree F. Has a power switch and F/C button under a sealed rubber flap.
