Although this gadget is mainly to keep the fridge smelling fresh (and it does), the reason I got it was because of the alarm to alert me when one of the doors doesn't close tightly. I have a three door fridge which I love, but one of the top doors doesn't always close completely. Being ajar even a little allows the light to stay on so the top shelf being nearest the bulb gets warm fast. Because the door is only open a little, I may not notice it and once it was like that all night causing various things to spoil. The fridge seems to know if the door is open for an extended period and turns itself off from perpetually running so that doesn't help either.
When I saw this gadget advertised, the one thing that got my attention was that an alarm would sound if the temp in the fridge got too warm. I couldn't get on the phone fast enough. I've had another temperature sensor that attached to the outside of the fridge with probes that supposedly attached inside with suction cups, but they didn't stick, the wires were in the way, the alarms were hard to set and if the thing did go off, I couldn't figure out how to turn it off without having to reset the whole thing. It wasn't effective and I eventually threw it out.
This thing is great. It takes batteries and shows the temp in the fridge in the little display window. When I open the door I can see what the temperature is easily and have come to expect it to be 38 degrees. There is a setting to have the alarm on or off in case you are cleaning things out and don't want the alarm to sound, but when the switch is on, it will sure enough make a sound loud enough to tell you the door has been open too long and the temp has risen too much. The alarm goes off immediately by itself when you close the door. I love this thing. Since I've been using it I haven't had any bad odors, but then that may just be because there hasn't been anything spoiled in there. I don't know. Maybe it's just working as designed. Produce seems to stay fresh for a good long time so it may be helping with that too. To me, both of those features are just extras. What I wanted was the alarm and I've been delighted that it's so effective. I highly recommend it over other gadgets to alert you to a door left ajar by mistake.
Update: I mistakenly thought the alarm sounded because of temp change sensed by this device, but upon reading the instructions (finally :) I see that the alarm sounds due to a light sensor on the device that knows when the fridge light has been on (therefore door open) for more than 60 seconds.
Of course I was skeptical, it sounded just like any other gimmick gadget. But since it was cheap I decided what the hay, why not give it a try. Well I was pleasantly surprised by the results. No odors whatsoever and my produce is lasting much longer. Paid for itself in weeks. I alos like the alrm to let you know if you left the frig door open, nice added feature.

the product worked fine but the way they were shipped wasn't. the package was ripped and the boxes inside were torn, it's a wonder that the filters were still useable.
