Some observations: -The interior and probe temperature are the same or very close when both the device and probe is in close proximity, so that's a good sign -When the probes of both units are put into the same area, they read very close or the same, so that's also good -There are complaints about the magnets not being strong enough. I'd say it's not that the magnets aren't strong enough, but rather the issue is the magnets are recessed behind a plastic ring and so the magnets don't directly contact the mounting surface. To fix this, I cut a rectangle out of a grippy material (like a disposable glove) and put it between the meter and the fridge surface. Stays put now. -The setpoints for the alarms must be based on Celsius because in Fahrenheit, the alarm setpoints are adjustable in increments of 1.8F. Weird, but for an alarm it's ok. Someone said you have to remove the battery to change a temperature that was set incorrectly but that's not true. I have changed the alarm temperature simply by going through the same steps in the instructions. -Some have complained about how complex it is to configure. I gave it to my 10 year old and he figured it out. I also don't believe it to be overly complex. -The beeper is not real loud, but it's sufficient. Maybe about like the volume of a countdown timer.

Would like it to go off if it gets below like 42 degrees. Would this work?** A: Yes this would work for your needs **Q: Does the Max min setting measure the highest/lowest temp during a set period of time? If so what is that time? 24 hours?** A: It measures the max/min temperature since you last reset it. **Q: Must I drill a hole in my freezer to use this item?** A: I routed the cord in back and underneath and ran it up thru the freezer drain hole . **Q: The definition of out probe and in probe are vague. if i'm using this in the freezer is the in probe?= freezer & out probe? room temp?** A: We have our control display on the outside of the refrigerator. The wired probe sensor is inside the refrigerator compartment and corresponds to the "out" setting. The "in" sensor and setting is within the display so in our case reads the room temp at the outside door. Hope that helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not perfect, but for the price pretty good *by J***R on July 26, 2025* I got two of these, one to monitor a fridge and one a freezer.

Works as advertised ### ⭐⭐⭐⭐ Very non-intuitive settings *by T***. on August 9, 2023* This product works, BUT, the settings and names that they use are very hard to understand. For example, they call the temperature probe that will be placed in your fridge/freezer as OUT. The external display is called IN. So strange to name them that way. Another odd one is the way you have to set the min/max temperatures. It takes some playing around with and KEEP THOSE INSTRUCTIONS! But at the end of the day this device does work so I’m giving it 4 stars, the deduction is purely for the interface/settings. I will update this review if the unit ever fails. ## Frequently Bought Together - Brannan Refrigerator Thermometer Digital - Fridge and Freezer Alarm Alert When Temperatures Drop - Ideal Fridge Freezer Thermometer with Alarm and Max Min - 2 Pack Refrigerator Thermometer, -30~30°C/-20~80°F, Classic Fridge Analog Thermometer Large Dial with Red Indicator Thermometer for Freezer Refrigerator Cooler - Digital Fridge Thermometer with Alarm Clock and Maximum/Min Temperature Function --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/42325640-refrigerator-thermometer-digital-fridge-and-freezer-alarm-alert-when-temperatures](https://www.desertcart.vn/products/42325640-refrigerator-thermometer-digital-fridge-and-freezer-alarm-alert-when-temperatures) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-26*
