Another fan

There is another whole house fan on the market that has 6 blades, is silver in color and looks very much like the big box store fan. That’s because it is basically a big box fan with six blades. The bearings are tiny, the metal very thin and the whole thing is bolted, not welded, so there is a danger of it shaking itself apart. For the extra two blades (which does nothing to increase the efficiency or airflow and an upgraded shutter), you are asked to pay two or three times more than the same fan at the big box store. Conclusion: FAIL! PS: it’s called something like “Zipper"

OUR JUDGMENT: Too expensive, overpriced, short lifespan, poor quality
