O2COOL Deluxe Hands-Free Wearable Necklace Fan Random Colors 4-Pack

Never leave home without one. They work well.

These O2 Cool Collar Portable Fans are perfect! Lightweight, colorful, and surprisingly powerful. They keep me cool instantly, and the 4-pack is a great value. Definitely deserving of the Amazon’s Choice badge! Highly recommend!

We bought these fans for our Disneyland trip on a nearly 90 degree day, hoping they’d keep us cool while walking around the park. They worked okay in cooler temps, but once it got into the 80s, the airflow just wasn’t strong enough unless we held the fan directly in front of our faces. Around the neck, it didn’t feel very effective. I paired it with a cooling towel which helped a lot - the combination made things more bearable. Overall, and for the price, it’s a decent option for light use or mild weather, but I’d prefer something more powerful for really hot days.

Love the size - worked perfectly for my 5 yo when we took it on a cruise. It was easy to adjust and turn on/off. Needed 4 individual fans so it was great it came in assorted colors.

If you feel the heat like I do, this little fan is a life saver! I've always sweated much more than I like and was always carrying something to fan myself. These fans, and I've had several over the years & literally wear them out, have kept me from feeling light headed from feeling too hot. It's a great little menopause buddy as well! They're quite quiet. I've had one become a little bit noisy but it was after being dropped several times. It still worked just fine but you could hear a small rattle. Not the device's fault. The battery life isn't too bad. It really depends on how often you use it. I use mine for several hours daily so might get 2-3 days from the 2 X AA batteries. Cheap batteries don't last very long at all. Remember to adjust the neck strap so you get the full benefit of the air flow. I love these things. You forget you're wearing it.

I did not realize these were battery operated. Fair enough. They do not have a good fan speed. You barely feel the fan. The size is good.

I heard these would be good for going to theme parks during the summer and oh yes they are. Literally lifesavers! If you are going to any theme park like Disney World or Six Flags during the hot summer I would highly recommend these. Especially if you're going somewhere humid. Really helps with the stagnant humid air. WEIGHT: They are very lightweight hanging around the neck. I hate wearing things around my neck and I never noticed it even after days of wearing it. TEMPERATURE: The fan only pumps air that's around you so no it will not 'cool' the air, but it still feels amazing. When you get into an AC'd building however you really feel the amazingly cold air blowing all over your face. It's like heaven. lol. BATTERY: The battery life is short because it only takes two AA batteries. I pushed the limits running it 8 hours straight and by the end of each day, I had to change the batteries because the flow was so weak. Just make sure to bring enough batteries for every day you're going to be using it. You could push it to two days but again the flow is very weak in comparison to having fresh new batteries in it. (I would love if the next model could have a rechargeable battery option because that would come in handy). SAFETY: Also, I have long hair and the blade did worry me being so close to my face. Don't worry! The blades are what I would call an open blade - if that makes sense?! My hair was only puled in a few times being careless and it came right out with no harm done. It's a cool looking blade that I wish we could use in every neck fan. NOISE: It is the quietest fan I've come across. You can hear a slight hum in a quiet room but it so quiet and lightweight that you honestly forget it's there. Recommending these amazing creations for the rest of my life! 😊

I have been using these for the last 9 years. Being a person, who tends to be warm, working in areas, which tend to be hot, the cooling breeze is necessary. Working as a cashier, unable to move around much m this was a necessary addition, at work. The ability to change the batteries, in a matter of seconds, is crucial. Just keep extra batteries in your pocket. I have tried the rechargeable types and they fail. Charge never lasts as long as advertised .

This little fan works exceptionally well to cool the wearer to a much more bearable temperature, without disruptive noises or discomfort. It is a wonderful, affordable, and comfortable find!

We bought them to keep cool on a trip to Costa Rica. They didn't really make much difference.

I like that this fan can be worn and adjusted around my neck and that I can move around while it helps me to stay cool.

Noise level is little loud

Excellent product very quite
