What buyers say about Dynarex Hot Pack
I was very disappointed that 7 out of 24 bags didn't work, because the material inside was very clumpy and felt like a bunch of sharp rocks in a plastic bag.
I'm able to pop them to spread the heat even though I have limited hand strength. They can be molded to the area you want to apply heat to.
I have been suffering with a broken spine for a long time and the heating pad is so easy that I don't have to worry about electric heating pad.
These are some of the best cold and flu products I have ever bought, and they are so easy to use, they are a must-have for anyone with a cold or flu.
I had a lot of pain in the hospital and the nurse would put one of these under my back so that it wouldn't bother me.
Common Questions
All of the bad reviews seem to be getting better, but there's no way to check them until needed.
I bought these twice in 2016 and they worked well, even though I was nervous about the bad reviews. I ordered another box because they were great for my daughter's surgery.
Will they pass tsa in carry on?
I am not sure how much liquid they are.
Is it a single pack or a 24 pack hot pack?
It's 24 packs and they work.
Is it possible to fly with these?
I would call the airline and ask if they could pack them in freezer bags and in checked luggage.
What is the last date of use on these?
I didn't see a day until the last few boxed I got, but they had the dates on them, so at least a year out.
