The thermometer and probe seem to be well made but it didn't work very well with my upright freezer. As others mentioned, the alarm is not loud enough unless you're fairly close to the unit but the biggest problem is the probe wire. It is round, about 2 mm in diameter and my freezer door will not seal tightly around it. Within 2 days, my manual defrost freezer had a block of ice forming where the wire came through the seal due to humid air leakage. I've seen other units that use thinner flat wire which I suspect would work better.

Great unit, but the alarm is wimpy. you would never hear it on the second floor of a home if needed. I modified the two CDN units I bought to make them louder. I can now hear them anywere in our home. I may publish this Modification in MAKE magazine if there is any interest.

The unit seems well made, for the price and the display is easy to read from a small distance. The only thing that needs improvement is the volume of the alarm. It is about as loud as a digital wrist watch alarm. You have to be in the same room as the unit to hear the alarm.

My freezer is in my basement and I would never hear the alarm from up stairs.

BTW, I have perfect hearing.

Have had it for 15 minutes so this is my initial review:
It would behoove this company to include some instructions because the major complaint
of the cable bulging the seal and letting warm air into the freezer is easily rectified.
(They would get more 5 star ratings if they did so - this is something the Chinese need to learn)

1.) Look under the seal and you will see some screws holding the seal in the track. Loosed a screw or two, and pull the seal out of it's track
and you can then fish the sensor behind the seal. I had to make a very narrow (maybe 1/8") snip in the back of the seal to get the wire past and to get the seal back in it's track. If it seems to leak, and I do not think that this will be a problem, a dot of silicone caulking will solve that problem.

2.) The suction cup will not stick so I hung the bulb from a bracket at the top of the fridge and tied up the excess cable with the include wire tie.

3.) Make sure that that when you open or close the door that the wire does not get under the seal anywhere. I will use duct tape or something if necessary to position the wire. but so far so good.

It shows the temperature fine. The sensor is sensitive and you can see temperature creep up immediately as you open fridge door.

Minuses:

1. Lack of a magnet. To see the temperature you need this thermometer mounted to a door or a side of your fridge. Why couldn't designers integrate a magnet to hold it? Boggles my mind.

2. Wire is way too thick. About 3" of seal is open around the wire. Why couldn't they use a flat wire? Boggles my mind.

3. The third minus probably relates to a small fraction of sensors. The alarm on my sensor goes off every 10 minutes for short 5 seconds, even though the temperature shown is below the set point. Why? No idea, probably defective electronics inside. Whatever it is, makes it useless in terms of the alarm.

On two occasions we lost everything in our freezer. It was in the garage and the door didn't close completely. This alarm would have saved us hundreds of dollars. Several times since buying this alarm it has warned us of the same mistake. It works and it's reasonably priced.

It works fine on our deep freeze in the garage. I even heard the alarm through the door on Thanksgiving day when our freezer had a glitch and cycled off and didn't come back on.

I ordered 3 of these units to keep track of the temperature in both refrigerators and deep freezer. The audible alarm is nice because it only sounds if the temp is too high or too low. Well worth the money.
