Super quiet easy to install works fine very happy

I guess you can keep buying the $79.99 one.You will learn the hard way. like me!Short and sweet because I don't do reviews often unless I am feeling obligated this item is by far more than exceeded expectations Yes it turns back on after you lose power Yes it pulls much more air than any of the other $79 fans at this price point this fan is by far the best ever ever ever I bought two.Not one regret if you're unable to come up with the extra money wait!This fan is night and day from the others you're comparing to.Excellent job Infinity

This works so much better than the ones i have been buying, i will buy another for my next one.

Much quieter then my last exhaust, smaller and much more powerful.

I am using this fan to help exhaust my boats adapted window air conditioner unit. It has been doing quite well with very little noise levels. It was quite easy to adapt to this application. I am sure this product can be used in a multitude of projects requiring enhanced airflow. I can't speak for its durability since I haven't had it working for too long. I will also add that I was very satisfied with the packaging and delivery of this product. As for a con, I would recommend having adequate space for the placement of this fan it is quite wide in the center. For me, that wasn't a con, but it could be a problem for those not having sufficient space, so make sure to take measurements.Over all, I totally recommending this product and company.

These fans are soo good and I wouldn't buy any other brand. I just got my third fan today since I love how quiet and reliable they are. I have 1 in my flowering tent, 1 in my veg tent and another in my closet. They use a lot less electricity than cheaper competitors and will save you money long term because of this. With my grow setup I try to use as little electricity as possible so to me These fans are easily worth the money. When you run these fans 24/7 then quality and power consumption are a big deal.I recommend AC infinity fans over any of the cheap junk fans for $50 or less, especially since you'll be replacing the junk fan in 6 months or less and in the end will be paying more than you would have to get the AC infinity fan.

Second grow tent addition to existing A/C infinity air circulation system. The best in the market.

Stop working after 2months and it was real noisy
