I purchased this fan because of its ratings and thought it would cover the area I needed it to. Not the case 70 ft range is great but I believe the blades size is a little to small for my needs. I will keep it, always liked Vornado.I will just use it some place else, really it's good for a maximum of 12' x 12' room mine is12'x 14' and I just need a little bit more power in my opinion.
