Operating instructions

I have trouble with the control settings,fans etc.. Still don’t know, maybe that’s on me,but hope to figure out…the instructions could be better.. this is the 6 inch fan obviously, but I had a 4 in and it only lasted just under a year and had to buy another 4” in which i hope that’s not the case in this fan. Seems like it’s operating just great as far as what i did figure out at the present time!

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..

Botched billing

The fan is okay, maybe a little louder than I expected but still ok.I’m giving it a 1-star because the billing was completely botched, not sure if this was Mars Hydro or Amazon, but this forced me to get a new credit card and wasted an enormous amount of time dealing with fraud claim which ended up being a false claim and having to re-do most of my auto-payments. It was initially billed the correct amount, $139.36, a couple days later I saw a pending charge for $59.73 without any vendor information which I reported as fraudulent, almost a week later I saw yet another charge for $79.63 and the next day the original $139.36 posted charge was reversed, but by then I had already received a charge credit and a new credit card.Why was the $139.36 amount for the fan split into 2 charges ($59.73 + $79.63) in multiple day transactions is beyond me, I was going to buy more accessories from Mars Hydro, but no more.
