HOLMES HAWF2030 Twin Window Fan with Comfort Control Thermostat  Product Reviews

"Do NOT buy this fan. It it so sorely underpowered that it only just moves the air in front of the blades. It's so impossibly weak that it's difficult to tell which direction is doing what! Spend $5 more on the Honeywell, just as all the other reviewers state."

"I bought this fan from Wally World for $20 and got totally ripped off. Luckily I can take it back. Yes, you can reverse the fan by pulling it out of the window and flipping it around. - Can you imagine engineering a product to do this rather than installing a reverse switch? The other bogus thing about this product is that it's super weak. Even on full blast, it barely creates a breeze. Total waste of electricity, and time. After reviewing a few other fans, I purchased the very similar, yet superior Honeywell fan which I kid-u-not, blows twice as hard and has a reverse switch on it. The Honeywell fan actually blows cool air in and out as promised. For $5 more, get the superior Honeywell from your favorite French Big-box store with a huge target on the front."

"I had the same "experience" as the other reviewer regarding "Manually Reversible". Basic fan with basic function. Returned it to buy Honeywell."

"The spec says that it is manually reversible. That actually means that you need to take down the fan, switch the side, and put it on back on the window again, just to change the direction of the air flow."
