Simple, effective, worthwhile dual-monitor device keeps tabs on temps of your fridge/freezer(s).
BOTTOM LINE: Affordable, simple way to monitor the temps in your refrigerator and/or freezers to insure that your food stays at the temps it should. Pop in batteries, set upper & lower limits and forget it. About as simple as it gets. Very happy. Well worth it for the peace of mind. 5 STARSTHOUGHTS: Having just filled our large chest freezer in the basement with a half Angus beef, I thought it might be a good idea to make sure things are staying at the proper frosty temps. Our freezer is decades old while it's always just chugged along without complaint, you just never know when it might give up the ghost. That'd be a helluva lot of perfectly good food (and money) gone to waste if it ever did. We don't go down there to pull food out or check on a daily basis so, after some internet researching, this inexpensive little remote thermometer seemed like a good way to keep tabs on things. As a bonus, this unit is set up for two individual sensors/monitored readings, so I placed the other sensor in the bottom drawer freezer in our fridge in the kitchen. Now they're both being closely monitored, so hopefully we'll never have any ugly surprises! Instruction booklet was helpful, but setting was an intuitive deal. Set upper & lower limits, decide whether you want an audible alarm for each sensor (about as loud as most cooking timer alarms) and place it where it's most convenient for you. (Receiver unit has a hole to allow for mounting on a nail or screw, a pop-out foot to allow you to set it upright on a counter or widow ledge, and 4 strong magnets so you can attach it to your stove or fridge. Main receiver unit takes 2 "AAA" batteries, remote sensors take 2 "AA" each. The manufacturer recommends using lithium batteries, for longer life. I'm not sure if regular batteries would last very long sitting in the single digit temps of the freezers, so I sprang for a set of Energizer Lithium batteries - just to be on the safe side.*** I also wanted to mention that when I got mine, I couldn't get a reading from Sensor #1. I tried different batteries and whatnot, but to no avail. I contacted the vendor (AMIR) and they quickly & politely responded with several suggestions, which I tried... but still no soap. I emailed them again and they offered me a complete refund and asked if I'd be willing to take a chance and re-order. I did, and within a couple of days the replacement arrived. When I put the batteries in, I quickly discovered that the fault with that first, original unit wasn't with the remote sensor but rather the main receiver/display monitor; the readout for sensor #1 was dead. Oddly, they said I didn't have to bother returning the defective original. So now I have a second one which only displays one reading, but rather than throw it away or let it sit in a drawer I simply used the fully functional replacement unit to monitor our freezer AND fridge upstairs, and now that original unit with only one working temp is dedicated to the big downstairs freezer. Now I can keep tabs on EVERYTHING being kept chilled or frozen. Win-Win! THAT is what I call outstanding customer service!
