## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect Solution for My Coop
*by Z***H on June 11, 2024*

I was looking for a fan to install in my chicken coop. There are lots of different routes to go and lots of different fan options. This product is a great overall solution-it is easy to set up and install, it has a battery, and it works. It checked all of the boxes. I'm glad I went with this product over others. It is plug'n'play.My chickens love it and now just sit in front of the fan all day.My only complaint is that if the battery fully drains, the fan does not automatically turn back on. You have to manually push the on button after the battery drains and is recharged--it won't know to turn itself back on when it gets re-charged. Not a big deal though.

### ⭐⭐⭐⭐⭐ Great solar fan!
*by M***B on July 27, 2024*

I am using this solar fan in my quail enclosure. The solar panel absorbs and stores plenty of power to run it through the night here in Florida. The speed of the fan decreases with less light but it still runs. I have the solar panel attached to my fence. The bracket feels secure enough, though I would obviously have to take it down during a tropical storm or hurricane. I used a 4” hole saw bit with my drill to easily install the fan in the nesting box section. It is great to have ventilation for healthy and happy quail! I definitely would recommend this product!

### ⭐⭐⭐⭐ Does the job! But test before installing.
*by M***A on October 10, 2024*

I'm so glad I installed this in our metal shed. The shed stays a lot cooler during the day and quickly cools down as the outside temperature lowers. My only complaint is that plastic fan isn't completely balanced and vibrates a little. I wish I had tested it before installing it so I that I could exchange it. It's not big deal noise wise, only that overtime it will cause the motor bearings to fail and only way to fix the motor is to buy a whole new ecoCalm Solar Fan.
