Update: September 2023. The fan in my Kulkuf stopped working in August after owning it for less than a year and only using it intermittently. I contacted the company and they sent a replacement after a few weeks, but it was the wrong size. I have asked them twice to send the correct size and they have stopped responding. So I have no working device and I consider it a waste of money since it lasted less than a year. I'm unable to recommend the Kulkuf based on my experience. There are competitors on the market now so I may try one of those. Original review: I have been using the Kulkuf for a few weeks now and the experience has been mostly positive. Shipping is from India and took less than a week to reach me in the U.S. The first unit I received stopped working properly shortly after I began using it. I was able to have a replacement shipped quickly, which I really appreciate; however, I had to pay the cost of shipping the faulty item, which is unheard of in my experience. The manufacturer should absolutely cover the cost of returning a defective unit (the post office even commented on this!), and for this reason, I have taken off one star in my review. As to the cooling properties, I find that the wristband does help some with cooling. I had expected to be able to wear it to bed; however, because it cannot be operated under the covers, I am reluctant to fall asleep with it on and accidentally activate it under the covers during the night if I wake up and turn it on half-asleep. For this reason, I keep it on my nightstand but would have to wake up enough to reach for it, put it on, turn it on, and then take it back off once done. This is the reason for reducing my review by a second star. I only wear the wristband at home (I work at home). I would probably wear it other places if it were more streamlined, but the current version is bulky, as other reviewers have noted. I don't use it during workouts as I wouldn't want it to get sweaty (plus, you're supposed to get hot during a workout). I use it for times when I don't necessarily expect to get hot. I wish it had a battery indicator, but that would require some type of display. I just have to remember to charge it every couple of days. It comes with a small travel bag which is nice.

I was super excited to get my kulkuf the first few times I used it I loved it. I wear it everyday but lately when I use it the Velcro doesn’t stick and after I use the blue cooling feature it then gets really hot on my wrist
