iapsales Easy to Read: Refrigerator Freezer Thermometer Alarm, High & Low Temperature Alarms Settings, Stainless Steel & White

The thermometer seems well built and the digital display is bright with good contrast and easy to read. It came in the mail in two days without any damage and after I installed an AAA battery (not supplied) it worked as advertised. When checked against a laboratory grade glass thermometer traceable to NIST standards, the thermometer was only one degree off at 0 degrees F. well within its specifications. The temperature sensor tip is 4mm (5/32") in diameter, x 25mm (1") long. The probe wire is round, 2mm (5/64") in diameter x 153mm (60 1/4") long and seems sturdy enough not to break in normal use. However the wires does get stiff at freezing temperatures. The display unit has a flip-out stand that is easy to open and a magnet powerful enough so that the display does not fall from a vertical (steel) surface or the top of a chest type freezer when the lid is opened and closed. Unlike many other devices I have owned, the lid to the battery compartment to this display is easy to open and close. The high and low alarm limits were simple to set and worked as advertised when I tested them. I do value that the alarm keeps sounding until the alarm button is pressed to re-set it. I have a chest type freezer and when I first got the thermometer I just ran the probe wire over the top edge and closed the lid. Some ice formed around where the wire entered the freezer, not a lot, but some. I followed another users suggestion and ran the wire under the gasket. In my case I could not pull the gasket from the lid without tearing the gasket so I pulled the gasket out from the lid, stretching it enough to expose the thin connecting web and using an ice pick, punched a hole and ran the wire through the hole. Problem solved.. no ice. I am a regular Prime customer and paid the listed price for this unit and do recommend it.

Works good. Bought 3 and checked calibration against other 2 other gauges. All 5 read within a degree of each other at 70F and 30F, so I trust this set is accurate enough for my needs.

Freezer alarm part seems to work great once set up. However: 1) I bought 2 of these. One beeps considerable louder than the other one. Not good. 2) Buzzers are located on the back and sound leaks out through some slots. When you mount it using the magnets, which most people would probably do, the buzzers are extremely muffled. Not good. In a high noise environment, there's no way you're going to hear it. 3) Hi-lo temp readings can only be reset by removing the battery. Not good. Not sure if this would knock out your freeze warning settings or not. 4) Hi-lo temperature readings can only be displayed by pressing a depressed button on the back. Inconvenient. Also, if you accidentally leave it on Min or Max you may begin to wonder why the thing seems frozen and unresponsive. 5) Setup is difficult and would be impossible without instructions as there's nothing you could intuitively figure out. None of the shortcomings are a deal-breaker for me. Not disappointed with main function of protecting my frozen supplies. It's reassuring when you open the door too long and the thing starts beeping showing that it's doing it's job. FYI, the sample rate is 10 seconds between readings, I suppose to extend battery life as it only takes a single AAA battery. Looking at reviews for some of the other freezer alarms, this seems to be the one to get. Hits right on that price/reliability ratio. Unless something weird starts happening, these are the ones I'm sticking with.

Have had this for almost a year and it's still on the first battery. alarm is nice and loud, and programming isn't too hard

Works good

hard to program

The included instructions are not exactly clear - however, they do work. The product also works, but it's not the most intuitive product. If you don't put the cable in before the battery, you get an LL error. It's in the manual, but still... Setting the alarm is kind of a pain. It only goes up - so if you go past the temperature you want, you have to wait until it cycles over. Not a huge deal, but annoying. My final issue is the alarm itself. It works but it is not very loud. My deep freeze is in the basement. We can't hear the alarm on the first or second floor of our house. Someone is usually in the basement, so not a big problem for my household. However, keep this in mind if you are not near the alarm.

I have used these in all of our freezers for years. Work well
