BLACK+DECKER Comfortpak, Wearable Cooling and Heating Device, Cloud White (BCWCC101-10)

I really wanted to like this. The idea is great, but it just didn’t deliver the experience I was hoping for. The unit didn’t stay in place well, which made it hard to get consistent cooling where I expected it. Even when it was positioned correctly, the cooling effect was pretty minimal and didn’t feel strong enough to justify the price. The design looks sleek, but functionally it fell short. Might work better in very specific conditions, but for wearable cooling that involves a lot of moving around, I’d look elsewhere.

I purchased this to use it for its cooling effect. When I first used this, it worked as described except for the battery life between charges; it was significantly less than indicated. However after only 2 months of irregular use, it neither cools nor warms but, the battery lasts much longer. As the manual states there are no serviceable parts, this was nowhere worth its purchase price and must now be discarded.

I have been waiting for something like this for a long time!!! This is an easy to wear and comfortable item that I use for warming up on a cold day or keeping cool on those hot days. I love the way it snaps on and off. So easy and secure. Really works well. It really takes the chill away and adds nice warmth. It also cools you off when and on those hot day activities like mowing the lawn or jogging, keeps you nice and cool. the temperature ranges work great! I would highly recommend this product. Its awesome.

I was bit skeptical of how effective it'd be given that similar devices from competitors like Embr and Sony are well double the price. So I was pleasantly surprised that it worked very well. As I own it for longer we shall see how useful this will be. One gripe is the ergonomics. The silicone holder doesn't quite work for me. It doesn't choke you by any means, but way it sit the metal plate is ever so slightly off from my skin which defeats the point of it all. Personally I find it much more useful to use it like a cold pack for that reason. If you can get them on sale it's definitely interesting device. Does what it advertises. Update : As I've just gone skiing with it when the temperature was -15F it failed to perform at all. Which was kind of expected but nevertheless bit disappointing.

This item will not cool you down and will make you feel like your choking because of how it sits around your neck. Somehow when I returned this I was assessed a damage fee when the item wasn’t damaged. Getting sick of the process and purchasing items that are not worth the plastic they are made out of.

Wasn't sure if that how the product work, but charged the ran it on cold and it didn't get cold just cool. Kinda disappointed by the product.

I recently tried out the Black+Decker ComfortPack, intrigued by its dual functionality designed to offer both warming and cooling functions. Unfortunately, the product did not live up to expectations. While the warming feature provides mild heat, it barely reached a level I would describe as lukewarm, offering minimal comfort. On the other hand, the cooling function was notably ineffective, feeling akin to the touch of ordinary metal rather than the soothing coolness one might anticipate. For those seeking significant thermal relief, this product might not meet your needs. It might be more effective to explore alternative solutions that provide a more noticeable temperature change for therapeutic purposes. In its current form, the ComfortPack struggles to deliver the performance promised by its marketing.

It works well but not for very long even on low, a couple hours. Disappointing for that reason specifically.

Such a disappointment. I really wanted this to work, it seems so futuristic, not a fan but this device that that cools you just by being in contact with your skin! But the hype does not meet reality. Yes the metal plate does get cold, yes it's small (size of a deck of playing cards) But... the cold effect is just not strong enough (had this during the June/July 2026 heatwaves in the UK). The lanyard is not adjustable so it's difficult to get it to stay in the right place at base of back of neck; it kept sliding down. And lastly for me the battery only lasted about 2 hours even on the least powerful setting. It should have been great but it just did not accomplish its task Will be returning.
