Very nice, quality, made to last
Really powerful little fan. It’s made of sturdy metal and feels like it’s made to last. The settings run 1-100 and it’s very sensitive/responsive when turning up or down. When on full blast it can get loud but that’s because it outputs air like a jet engine. You can probably find cheaper fans that are similar size but this one is probably the best quality you’re going to find.

This fan is fantastic, 1st. its small, the size of a mayonnaise jar. 2nd. one piece aluminum housing. 3rd. set at 15% power, the exhaust side air made my wife's hair move from 8ft away. 4th. at 15% barely hear motor running, i walked away from it, forgot it was on. at 100%, it blew all the papers off my table from 8ft away. yes at 100% it is loud, but when you see and feel the power this little mayonnaise jar sized fan has, you will say holy crap!! The plastic bodied exhaust fan that i replaced is a popular name brand, i was running the old fan at 75% and the 2x4 grow tent was still hovering close to 90 degrees. i would have turned the fan to 100% but at 75% i could hear fan from another room across the hall. I had to put my hand over the exhaust port on the outside of the tent to make sure that the old fan was exhausting properly:( This little 4" fan will do the job better than the name brand 6" fans and i bet it would give most 8" fans a run for their money. 5th. the controller is small 1.5 inches x 2inches, compare that to the popular 4x4 inch competitor controllers. So when you compare cost of unit, air movement, quietness, cost of operation, the 4 inch turbo exhaust fan cant be beat. For tents larger than 6ftX6ft, Turbo Exhaust Fans come in 6 inch and 8 inch sizes. The only negative i could see is the controller power cord end plugs. Both plug ends have a 3 pin male/female connection. The connection is a tight fit, the power cord plug pins could get bent if you are not careful plugging the controller power cord into the fan and the controller. Be careful! I hope this review was informative.

Good Value for the Price
Using this to vent fumes when soldering. I like that it’s small enough that I can mount it on the wall with only push pins. Lightweight but sturdy. I would have given it five stars but it’s a little loud. It does the job. There’s no smell at all in my room after soldering.
