What is the temperature range these are approved for? I live in Chicago, so, I need them to survive Antarctic temps from time to time.

I live in Thunder Bay, and we had many weeks of near -40 below temperatures. Remarkably, these units work. I am exceedingly happy with the units I have purchased. I have owned them for more than one year now, and while I changed out the batteries, I fully expect another great year.

Were I live definitely does not get as cold as Chicago for extended periods of time but we do occasionally dip into the single digits for a week or so at a time and during those times they have performed perfectly always coming on. We are in 30's and 20's most nights during the winter and they work fine never had any problems with them not operating in those low temps. They have worked perfectly in the snow and rain with no issues and have had them installed for longer than six months and I am still using the same dollar store batteries I put in them when I first got them.

I bought these in Feb. 2014. Live in Colorado and it does get cold here. To date no problem with them working in the cold. I am very happy with this purchase.

I live in the Phoenix area, so my version of winter is probably different than your's ^^. I suspect these will probably work best for Spring and Fall in cooler climates.

Yes, they will work get in any climate. I have used them in both extremes, cold and hot over extended periods of times.

I don't know exactly how low they will tolerate but I've had mine out in minus -20 degree temps without any problem, its best to use the external 6 volt lead acid battery in its weatherproof enclosure, I also cover the battery case with a plastic bag, this is what I do, I live in upstate central NY , Good Luck and if I can be any more help, just ask Sincerely Mary

I think about room temperature should be fine. These are fungal spores so I imagine they are incredibly resilient to temperature changes.

I use them for pre- and post-season driving in my convertible. I've had no trouble with cold seeping in - including highway speeds in low 40° temps. Unsure if using them in true frigid weather would keep you warm enough - but then again, layering is always best.

They do not have a temp rating. I was just out in -30 temps with two base layers on under these pants and I was relatively comfortable.

SPEC'S: Avoid temperatures below -10°C (14°F) or above 60°C (140°F).However, I tried it in my great cold City of Chicago last week when it was below 0, and it worked......barely.

My pleasure. They are my favorite "survival-energy bars!!" They keep in all kinds of weather. Freeze them and crack them. The best!!! Bo

We are in Australia and have been using these alarms summer and winter, lowest here would have been -2 degrees. As long as you use non rechargeable batteries they should work fine

According to the manufacturer: Durable, zip-close re-sealable packaging; withstands extreme conditions and temperatures (-22F to 149F). I bought these specifically for my car since they can withstand extreme temps.

I have mine set to a temperature of about 40 degrees F. No ice build-up yet, 3 months and running. I'm happy with my purchase.

I wore these under trousers and jeans in winter in Australia so it's not usually colder than 9-10 Celsius in the morning outside.I would say 3-4 perhaps but I bought them as a buffer against cold not as a thermal. I really liked them .They are not something that will do the same as thermals 100% but for taking the chill off they're great.Keep in mind the quality is not long lasting sadly and they after 6 months had to be thrown out but they're long in the leg and higher waisted than others.

Hi, We live in Chicago and it has been working just fine in the cold weather. No Problems! We have already had 10 degrees and its perfect. Its really worth the money.

They do have a heat rating. I assume if you keep it under the correct temperature you should be ok.

Has anyone used these for their dogs? I have two very furry pups. They are suffering as soon as it hits around 75 degrees.

not sure but check to see the recommended temperature guide. I wanted something for as low as 20 degrees. That was the selling point for me. They were a gift for my grandsons birthdays.
