Review: Coold great. Over a year, hasn't let me down - I purchased this a while back, maybe over a year ago to keep a light cool. It works great and has never let me down. I run it 24/7 for probably over a year now. Keeps light temps from 108 to 82. Great quality
Review: I dig it - Love this brand, easy to setup and to use, worked out the box. looks nice, matte housing with a gloss faced nob matte sides comfy grip and feel. The nob turns smoothly, there’s no play, responsive, there’s no delay. Comes with mounting bolts and nuts and wood screws of nice quality, black coated matching the color of everything else. Lovely

### ⭐⭐⭐⭐⭐ High performance fan in a small size
*by A***Y on October 10, 2018*

This review is for the AC infinity 120 mm AC fan and controller. They are a perfect combination and as a bonus, the controller comes with cabling for 2 fans, so it can daisy chain at least 2 together. I needed mine to point in a specific direction, in my case, I use to help cool an air pump for my plants. This unit works perfectly and the frame I made for mine makes it even better. It's very adjustable now and real easy to adjust flow. I've been running it on the lowest setting and it seems to be right on. It's nice to know that there's plenty more power if I need it. If you need a fan that is durable, compact and versatile, this is it!!!
