Fan prop is made of THIN aluminum which is warped out of the box and can warp more, why does this matter? Well, for starters it leads to an unbalanced prop that causes uneven baring wear and premature failure. Secondly, the unbalanced prop also lead to regular intervals of a terribly annoying and loud humming sound. Thirdly, this also produced a terrible burning smell which triggered my asthma repeatedly, after a month it didn't go away.
I contacted Lasko for a replacement, I was required to cut the controller and power cord and ship it at my expense to their warranty division, I haven't tried to recoup 8 dollars for that as of yet as per their warranty instructions on their website... They were very helpful over the phone, unfortunately however the replacement I received NOT ONLY had a gouge/dent on the outer area of the fan blade, but it was missing a screw! The only improvement is that it hums less frequently and isn't smoking me out, this will still lead to a premature bearing failure due to uneven wear, I am 100% unsatisfied and will not be buying another aluminum/steel fan from Lasko. Why is this important you ask? Because it's very clear to me, especially given that I cannot find a quality assurance sticker on either box nor fan, that there is little to no quality assurance.
I was a fan of the 2250QM 8 years ago, but I suspect any remaining stock of that older model was changed to accommodate the substandard wafer thin fan prop. I have used HVF for years in my residence as I prefer the white noise and the air movement, so I can tell quite easily that this fan will not last and either due to incompetence or by design will fail prematurely. One is a fluke, two, especially with a glaringly obvious gouge in the prop is incompetence and only underlines not only poor quality materials but no quality control at all. (The replacement came from LASKO not amazon, so it is not restricted to the sellers stock here.)
This is a tragedy, this entire issue could have been avoided if not for some greedy executive opting into using substandard material on the prop of all things which I have never seen and for good reason. If someone at Lasko reads this, I hope it was worth saving short term cost, because you're going to be experiencing a high RTM from sellers and or customers and comping replacements and shipping fees. I find it shocking that I am the only second reviewer to complain of this hum, I presume people are leaving these in their garages or something and not sitting in the same room for extended periods of time. To reiterate, I have owned several HVF in my lifetime, these are atypical sounds and symptoms.
