Review: good quality - great product; works well
Review: Works great so far - I've only been testing this fan/filter for a few weeks, but so far I'm very happy. It moves a ton of air in my 4x4 and the fan (which I installed inside the tent) is decently quiet when cranked up to max settings. It was very easy to assemble and install, and I have no experience with these kinds of things. I did opt to seal the ducting with aluminum foil tape in addition to the hose clamps -- the tape needs to be bought separately. That said, I don't know if that's even necessary. The smart monitor is REALLY nifty. Tons of settings to automatically adjust for different scenarios when certain conditions are met. When I thought I had a problem with the monitor (it was actually just me being dumb though) customer support responded to my question in a few hours. Really can't complain! I'll try to update a year or so down the road and let you know how well it ages. In the meantime though, I'm a happy camper..

### ⭐⭐⭐⭐⭐ Powerful fan with automation, serenity.
*by J***S on May 6, 2021*

This is quite possibly the best in line fan ever. Not only does it completely sustain a 3x3 tent, it literally sucks the humidity out of the whole room as well. The fact that it has a temperature and humidity sensor just sends it over the top. The mountable controller makes changing settings a breeze. The automation is a must have, I do not know how was running a fan full blast 24/7 before. Probably because there was no solution like this out there. Mars Hydro has really outdone themselves this time. Top of the line fan with a great controller. I will be ordering more for my other grow area. I can honestly say that Mars Hydro products are some of the best in the game right now. They have come a long way and continue to impress me.
