"Initially, I was disappointed in the size, but that's on me for not checking the measurements. I sweat a lot on my side of the bed, so I decided to try this little fan. Wow! I start on the first of three settings and move up as I get warmer. It's amazing how effective it is, and I love that I can tilt it. We even took it to an amusement park, and it helped immensely! It's durable and worth the cost!"

"I got this fan for my exam room where the air gets stagnant. This little champ moves the air around enough while I'm at my keyboard so I don't appear too sweaty in front of my patients. It's small and unobtrusive, and quiet enough not to distract me from what patients are saying. While it doesn't replace the air conditioning, it's an excellent product for the price."

"I purchased these fans to cool my 700 watt surround sound system receiver that generates a lot of heat. After testing, I found that the fans significantly improved the temperature.

I highly recommend these fans for anyone looking for extra cooling."

Overall, this fan has surpassed all my expectations!"

I’ll definitely update if anything changes."

"I was quite surprised by how much air this small fan moves. It's perfect for my nightstand and doesn't take up much space.

It's a great option for anyone looking for personal cooling!"

"I got this fan to help cool my overheating Roku stick behind the TV, and I plugged it into the USB port on the TV. It turns on and off with the TV, which is convenient. The sound is pretty quiet, and the adjustable frame makes it easy to direct the airflow. So far, it’s a good value and works well!"

"At work, I use this fan at my desk, and it performs absolutely fine. My only issue is the on/off button being on the back; I often have to turn it around to access it. Given my desk setup, this can be a bit tricky. If they could redesign it to place the button on the front, that would be a big improvement!"

"I purchased this fan to keep my PS4 Pro from overheating. After cleaning the internal cooling fan, it still got quite hot during gameplay, so I decided to use this to pull away excess heat. It really does keep my PS4 cooler and prevents the internal fan from overworking and making that loud roaring sound during intense gameplay."

"I installed this fan behind the screen of my Android-powered head unit in my Jeep Compass. You can't hear it while driving, and even on high, it's still very quiet. It pushes a good amount of air and the setup is easy with the long cable."
