shinicWindow Fan with Reversible Airflow Quiet, Twin 9" Blades, Full Remote Control, 3 Functions-3 Speeds, Bathroom Kitchen Window Exhaust Fan, Width Adjustable (From 23.5" to 37") ETL Certified

This window fan really impressed me. The twin 9" blades move a lot of air, and it runs quietly enough to use in a kitchen without being annoying. I love the reversible airflow and remote control, makes switching between intake and exhaust super easy. The adjustable width fit my window perfectly, and setup was a breeze. Great value for the features!

This fan is of excellent quality and does a great job of air circulation. Having three fan operation modes is a great feature. I use it in an upstairs bedroom dormer window and it fits in well with the accordian extensions and a bit of adjustment. The fan has a bit of noise on start up but becomes quiet very quickly. The remote control works well and is a convenient feature to turn the fan on and off from in bed. A good product.

Fits perfectly in window, brings in the cool air and is very easy to use. I like the option of intake, exhaust or circulation. Works very well but can be a little noisy if you're someone who needs quiet (I'm a need fan noise sleeper so fine for me).

I have in-window air conditioning units. Last summer my electric bill was horrid, so I figured this year I'd try something different. This fan has multiple functions (cool, exhaust, circulate) and three speeds. It's been super helpful on moderately hot days, surely saving me a couple of bucks if not more. It is not silent but its noise level is comparable to an average fan. I live in the Eastern US with summer temperatures averaging around 80°F to 90°F. Obviously for super hot/humid days I'm still going to use my a/c, but this fan is a nice alternative. Recommended

This fan is very powerful. I mainly install it in the room for exhaust. The fan is very quiet. Basically, you can use it 24 hours a day. I am very sensitive to air. Because there are many dust layers in the room, you can use a flashlight or see the dust layers in the air under the sun. I use an air purifier, but it doesn't make a good improvement. When I use this small fan, the air in the room instantly becomes as clear as outdoors, and my nose is no longer allergic. If you feel that the indoor heating is a bit stuffy, just gently press the cool or cirulate on the remote control, and your room will become very comfortable. In fact, this thing can be used in all seasons, except rainy days. This is a product that is very helpful to your health and living comfort.

All of this fan's features are great - circulation mode, exhaust mode, the remote for ease of use, the depth is one of the only fans I've found skinny enough to fit in my window frame without busting the screen out of place... However, there is a dreadful hum that I just can't cope with. I enjoy background noise - white noise, brown noise, the hum of air conditioning units in hotels - I like them all. But the noise this fan emits is not soothing nor comforting and I cannot recommend it, especially if kept in a bedroom window within close proximity of your ears.

At first glance out of the box, it appears to be very cheaply made. It is indeed lightweight and do not expect it to stand up to any abuse but well worth the price. The side expanders do not lock out very well but do good enough to block air from going around the unit in the window. The circulation mode ( one fan air supply and other exhaust at same time) is a very nice feature when used in a closed room where the fan would have to fight air pressure buildup in the room, it probable does have a tenancy to pull in exhaust air in that mode but not enough to make much of a difference, still pulls in air and exhaust excessive air in the room ( possessive air pressure buildup ). this can also be prevented by leaving door open enough to let some air escape the room easily. Not silent but much quieter than any other single fan I have used. Knowing what I know now, I would defiantly purchase again.

I got this fan today, unboxed it, and installed it. This is great, in concept only. There were multiple issues I found with the product upon installing and using, First of all, the overall plastic covering the fan is rather flimsy. If looking at the back of the fan, you can easily see the plastic is not straight and is curved. That's not a big deal, but its something to consider.Next, the extenders. The extenders are plastic as is everything else. However, the biggest problem with the extender is unable to lock it in place. There are a total of 11 increments you can choose to adjust the length to. However, the lock doesn't lock it into place because of the flimsy plastic material. A little nudge or push and the extender shrinks again. I put my fan vertically so its standing. The extender cannot support the weight of the fan and there's no way to keep it in place. I literally had to use tape and tape the extender and lock so that I could keep it in place.I've had the fan running through the night. The overall noise of the fan is quiet, as quiet as a fan should be. It is rather powerful. HOWEVER, every once in a while, there will be a noise coming from one of the fans, like it's a loose blade hitting on the plastic or something. The sound comes and goes.I wanted to like this product. If it wasn't for the above mentioned flaws, I think this would be a great product. Some other reviewers also has similar issues so I'm assuming its not just me that has had to deal with this. This shouldn't have to be a gamble and take your chances on a product with risk of getting a bad product with flaws. It's too much of a hassle. There's not enough time in the day, we don't want to buy a product and it comes with problems. Maybe another brand would have better quality...
