About World-BIO Body Warmers for Cold Weather, Heat Warmer Patch Disposable with Adhesive Backing
Overall Feedback:
75% positive
72% praised the battery life, but 28% found it ran out quickly
I compared the battery life of my new hand warmers with an older set that had expired in 2018. The older set lasted almost 10 hours while the new ones barely lasted 3 hours.
After opening 8 of them, I noticed that they did not get warm after an hour.
68% liked the ergonomic design, but 32% found it unattractive
The camping-hand-warmers can be stuck to your body or clothes, which is a huge benefit as they don't fall off.
I was disappointed with the product as it was not what I was looking for and did not even get warm.
66% appreciated the intense heat, but 34% found it mild
At 10 degrees, using 3-4 of these at night can ensure a good night's sleep.
One of the warmers worked well for a full 12 hours, but it was too small for my needs.
The first hand warmer took 30 minutes to get warm, not hot, just warm.
74% praised the high-quality materials, while 26% didn't
The patches are easy to use with no noticeable smell. The adhesive back stays in place and they provide warmth.
The camping hand warmers can be stuck to your body or clothes to prevent them from falling off.
Carbon's active ingredient is now coming from Asia with a lack of US quality.
75% liked the portable design, but 25% found it bulky
I bought the product for an emergency kit for reptiles and ended up needing it sooner than expected when the heat stopped working at 3 am.
