Fan Vivosun :Très bien et silencieux.

So, I'm using this fan as part of my custom built ventilation system in my basement room converted to a cigar room. I use it to suck the cigar smoke out through the window via the 6 inch hose and some ducting that goes out. I use it in conjunction with a duct fan that's hooked onto the HVAC ducting that acts as an intake fan for the same room. What I like. 1. The speed controller comes attached. No need to purchase one separately. 2. Durable. I had a mishap where I accidentally dropped it from 7 feet to a concrete floor. No problems, turned it on and fired right up. It's plastic on the outside, but the fan itself has some good heft to it. 3. Powerful. This thing cleans out a room fast. You can watch the smoke going from the cigar a good distance away in the room as it goes right to the area of the fan. What I don't like: 1. This thing is loud. But, that's the compromise. If you want a proper fan that will do the job, noise will be on the table. That all said, it's not loud enough to drown out conversation or music on a small speaker in the room. Further, it's powerful enough to run on low and still keep the room clear with one or two cigar smokers. In all, this being part of my ventilation system saved me hundreds of dollars by not buying a rabbit, or any other overpriced smoke eater. Good price, quality fan.

Bought this to replace a chintzy 6 inch inline fan that was squealing. It Arrived quickly, well package, and moves air very efficiently. It is quiet and well built. Mounting plate is easily installed and holds the fan securely. Everything about this fan is 5 star BUT, I just installed it, so I can speak for it's longevity. Based on everything else, I would guess this fan will last a long time and work well the entire time. I'm glad I paid a little extra for it and would make this purchase again.
