Good inline fan
Had problem with it turning on and off but downloaded the updated version software from the app and it works good.

Deceptive marketing, this by itself cannot connect to your phone as images indicate
Warning: this company practices deceptive marketing, illegal in some countries, like Japan. After receiving this, following the manual, and downloading their app, I was unable to connect. After searching for how to reset the fan, I found a video that had the process for resetting the fan burried among how to reset other devices. Nowhere in the product details, the included instructions, or the video, do they mention you need to purchase another USB devicd in order to connect. It took days for me to finally learn this, after submitting a support ticket, and speaking to two different agents. I should have read the other reviews!

Convenient
Love being able to check on my phone what’s going on in my room. Control and set up from phone is good. The settings portion could really use some work as can the manual they give you. It doesn’t really explain how the features work. That can really use some work.

Good quality
I love the sleek stylish design. The powerful motor is a lot quieter than other big brand name inline fans. Perfect for my 3x3 grow tent, this circulates the air exceptionally well.

Does not work as described
The app for this fan and reaction from fan by the app is confusing and does not work as they say it should. It's either run like a fan all the time or use limit switch. However the fan will not work with limit switches at all. It just runs all the time. The app is super confusing with strategy switch limits as they don't work. Been trying to have it work with mars for 2 months, still does not work. Same with smart lights.. they don't bind to wifi when more than 1 smart light and do not work as a Daisy Chain. Mars has allot of work yet to be leader in smart tech.
