### ⭐⭐⭐⭐ Much quieter than comparable fans
*by D***J on May 4, 2024*

My house is around 20 years old, and the original Braun fans were getting old and noisy. Since I have existing construction and the four fans in my house are near impossible to get at due to their placement under decade's old insulation, I decided to purchase some replacement fans that could be replaced without having to get in the attic. The Tech Drive bathroom fan, at first glance, checked my boxes: I needed something easily installed, and I wanted something quieter than the jet engines that were the Brauns. They were about 20 dollars more expensive than the Brauns, but if they were quiet and easily installed, it would be worth it. I bought 4. The first two were installed without issue. The hardest part was having to partially disassemble the Tech Drive fans so they could be installed without having to get into the attic or crawl space. But I got them installed, turned them on, and glorious quiet! These fans are significantly quieter than the Braun fans I had before. Probably 1/3rd of the noise of the Brauns. My kids noticed immediately, they thought the new fan wasn't working because they couldn't hear it. With the Brauns, I could pretty much hear them running just about anywhere in the house. With the Tech Drive fans, I had to be right next to the door of the bathroom they were installed in. Super pleased. Went to install the third fan, and unfortunately, I was met with an issue. The little door that sits inside the plastic exhaust had broken off the pivot. I didn't notice until I got the fan installed and turned it on. It was really loud and I could feel air blowing back into the room from it. That's when I disassembled everything again and discovered the broken door. Bummer... Had to take the whole assembly down, box it back up, and return it. Fortunately I had the fourth fan, so I put it in instead and it worked fine. But now I'm short a fan. Amazon is awesome as usual and is sending me a replacement without a problem. Bottom line is, these fans are really nice. They are quiet and easy to install. My only issue was the broken exhaust door, and the reason why I left four stars instead of five.
