### ⭐⭐⭐⭐⭐ Mars hydro I fresh
*by A***R on April 19, 2025*

This was a great upgrade Bluetooth control is awesome

### ⭐⭐⭐⭐⭐ Good quality
*by L***R on December 24, 2023*

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.

### ⭐ Deceptive marketing, this by itself cannot connect to your phone as images indicate
*by C***. on April 30, 2026*

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!
