🌀 O2 Cool 8-Inch Eco-Friendly Fan Review

Work well, pack it when staying in hotels. I need noise to sleep. I noticed that after 3 nights of operation it got louder (rattling noise) which was a bit annoying. I would not buy this product again.

Small but very powerful. I even only used it in the first setup. It also has such a small footprint that it's great to sit on my desk. The lady who works the other shift in my cabin loves him as much as I do!

My wife loves the fan noise when she sleeps. Bought to replace a failed 80 watt fan. The noise is different, higher. But she's happy with it and I'm happy with the energy savings. She also takes it on vacation to sleep better, so the small size is good.

After receiving this pink fan (oddly you can't choose a color), it's too flimsy for a nearly $30 fan. I was going to buy this fan from Harbor Freight for about $8. I've found performance to be low, but it's just a flimsy piece of plastic that barely blows air on high settings.

Expectations really depend on how much you spend on something. It's a cheap plastic fan. But it moves quite a bit of air, especially considering how little power it uses. It's small and quiet. I put one of these in the closet to move the air along with a dehumidifier. It works continuously, 24 hours a day for six months.

I bought this to replace the small clip on fan I use in my camper. I really like how it folds up for easy storage. It also moves a decent amount of air and uses very little power. A bit noisy, but not critical in my opinion. The price is reasonable and Amazon delivered it to me in less than 48 hours (at best). All around cool!

I sleep with a fan at night. I used to sleep with an industrial size fan that could blow bark off trees but my girlfriend hates fans and I had to scale it down. This fan works great. It blows very hard for its size, the angle is adjustable and it folds to fit in a gym bag or suitcase. The power cord can be detached from the back of the fan for easy portability. It worked so well I bought three more for my sister and nephews who love this little thing. The only problem I have is the fan speed…
