Have had this unit installed for about 2 months now and it has been performing perfectly. Quiet and powerful. Comparing it to a RadonAway name brand fan, I'd say the outer casing and flexible adapters are a bit thinner and "cheaper" feeling on the vevor than on the name brand, but the motor/fan/bearings, the parts that matter most, seem to be very good quality. At the price on this website, I'd say the Vevor represents an excellent value. It's cheaper, much more powerful (and quieter) than the cheapest RadonAway fan.
