    Seems to work fine, BT connection is horrible, App needs work
    I live in South Central Texas, and am trying to fight the heat and HIGH electricity costs each summer brings to us. I live in a one story, 2500 sq ft house, but my attic is MONSTROUSLY large. So much so, its ridiculous. I recently had a new roof put on to include ridge vents. That's a story for another time. While doing this, I discovered my front gable vent was blocked off. Why? Just stupid, so I took it down, redid it, and opened it up. That helped, but not enough air was flowing. So I made a duplicate for the back of my house, and attached this fan to it.If it hadn't been for prime day, I would have bought the red one, but since this one was on sale, opted for it. I did want the 3 speed and energy efficient motor as well. It was easy to mount, but the location I had it in, and being 60, was not easy. But that is not a hit on the fan and its mounting, more myself. First though, I had to run a 50 foot wire and install a electrical plug for it, and that was the easy part. The fan does what it says it will do. All three speeds work as they should, and the temp sensor/reader on it is only 1 degree difference then the wifi thermometer I have in the attic already, so that is good.I did pay attention to the reviews and paired it with the app on my phone FIRST before hauling it up to the attic. This is the year 2023, NOT 2003 and I can't believe for this price, it is not wifi enabled. I can connect about 25 to 30 feet away and even then it has to think about it and often multiple tries, but it finally does connect. What the heck Quiet Cool? For this price you couldn't include wifi? Wow.And the App. Why, of why, will it not keep any history? Absolutely amazing. I have a BLink thermometer/timer that is wifi and it tells me EVERYTHING. Again, if this was $100 or even $125, no problem. But I paid a premium price for this 'smart' fan, which turns out isn't that smart at all.Noise? Oh yeah, but we have a covered, screened in patio and you can't hear it when it is on high..unless you go out from inside it into the yard, then we can. The air this thing blows is incredible. And it serves a secondary purpose of keeping leaves from gathering in the corner of the patio roof. Inside the house, only at night when every one is sleeping and I am sitting in the living room can I faintly hear it. On medium and low, not a sound.BTW...as mentioned, my attic is huge. Dragging this thing that distance was much easier by leaving it in the box. Now, I am a retired Marine and do like to munch on an occasional crayon, so if I had been thinking at all, I would have placed it thru the whole in the outside wall first! DOH! That was my Homer Simpson moment. Regardless, it is hot as H-E-L-L right now in Texas, so I am not for sure if this is really going to make a huge difference or not. I hope so, time will tell and I will update this review. Another reason I bought it was for the 15 year warranty. In 15 years, I will be 75 or pushing daisies, so that is a long time. I hope it truly does last that long....I have my doubts though, will see. I really wanted to give it 3 stars, but it is made quite well, just lacks in functionality. I will update this post in time.Good luck and stay cool!UPDATE: I decided to give it 3 stars. The Bluetooth accessibility is just ridiculous most of the time. They should have sprung for a $5, 2.4 GHz WiFi adapter. Very cheap and lame, especially for this price!UPDATE: Finally received my CPS electric bill and it saved me over $100 this month. With the average temperature being 2-3 degrees higher in the month of July 2023 from 2022, it has seemed to do it's job. So that's a big win for my AC and proof that the electricity it uses to run is FAR less then the electricity it saves. The connection still is extremely lacking and poor, no data collection, and no timer functions as a set for off and on at any certain time each day.UPDATE: As time goes on, it seems to get louder and louder. Again, on medium and low, not a single sound can be heard. But on high...it is a low, thump...thump sound that is constantly coming from that side of the roof/ceiling. It was mounted properly, no doubt. Going to be a real PITA if I have to pull it down and add EXTRA rubber grommets to it again. And again, the connection is completely hit or miss.UPDATE: Received my August CPS electric bill and although the August temps this year were much higher (record breakers since 1880) than last years August temps, my electric bill did drop once again. So it has made it worth the initial cost of the fan. We also feel that our AC is coming on much less now and our house stays cooler later into the morning without the AC coming on. Our July and August electric bills have dropped well over $125 a month from last year's bills, and the temps have been almost unbearable in Central Texas. It is still noisy and makes a whomp-whomp sound on high, and the Bluetooth connection is still very stubborn and unreliable, but I do not regret buying it. It has consistently dropped our temps in our attic at least 10-15 degrees! Fix the connection issue (wifi) and include some better mounting grommets, and this would be a 5 star item.

    5.0 out of 5 stars incredible machine and company
    Reviewed in the United States on December 18, 2023
    A great company, based in So. California. Great service and sales dept, as well as support. A great machine, that is a plug in, and uses bluetooth to connect, depending on the size of your house you might have to move around to connect. Maybe they will offer wifi, or some relay or something in the future. But this is great...and you can check the tempi your attic, to get some idea of what its been like over night.... all kinds of features. Low, med, high, schedule, timing based on temp or humidity and all kinds of info. Installation is incredibly simple and basic.... and it is a regular plug in!! Meaning its as simple as installing the fan where you have decided to locate it, (basically screw the fan into its opening), plugging it into a standard outlet (the cored is 25-30 ft long I didn't measure it exactly) downloading the app to your phone, learning it and setting it up....and your fan will be working away. Enjoy!!!! I highly recommend it, especially if you have an old one that is so out dated you have no idea how to adjust the settings manually and it goes off & on almost randomly - like ours was - THIS IS FOR YOU. And if you just want more control, so you can learn how to set and control your homes environment ...this is for you.
    We are very happy with it. 👍👍👍
