About a year ago, I had purchased one of the Mars knockoff AC infinity fans, with digital controller for my indoors 2x4. I'm not sure why I chose the Mars over the AC? Maybe to "be different"? It wasn't much cheaper. It claimed to have all of the same features of the AC version and even the instruction manual was basically copied word for word compared to the AC manual. So I went for it.
Turned out that the fans have (or had) a flaw where they cannot be calibrated if they are off by a decent amount on the temp and RH. Even though it states clearly in the user manual that they could be. This really bothered me since I obviously have hygrometers IN the tent, but I wanted to be able to see a readout on the wall since the tent is used indoors. I needed that feature. If the readings were off by a little bit that would be cool, but they were off by a large margin.
I contacted them and they sent me a new digital controller. Same issue. Then it came to light that the feature wasn't working on any of the controllers and they didn't have any "real plans" to fix them. But they were still selling them and advertising the feature on Amazon. During this ordeal, waiting to get this resolved, my 30 day return window expired on Amazon.
I was offered a single fabric pot, and an in tent hygrometer for my troubles. LOL, I'm a grower. I have fabric pots and hygrometers coming out of my ass! More than that, I was insulted.
I contacted Amazon and provided a copy of the emails stating that the fan does not work as intended and Amazon agreed to take the fan back, but they charged me a restocking fee since it was past the 30 days.
I bought an AC version and it's been flawless.
I left an honest review of the product on Amazon including the fact that I was offered $5 in compensation. And then I started getting stalked by a Mars rep who told me I was ruining their business due to the review and that my review was going to cause her to lose her job. Emails had lots of crying emojis in them. Weird.
She DEMANDED that I remove the review. When I asked if they had fixed the controller issue and if it worked as they were advertising it, she became more aggressive. She finally offered me $20 to remove the review, and I still refused. The only way I could get her to stop emailing me was to threaten to report them to Amazon. Which I did end up doing.
Worst part is that all of the former 1 star reviews were changed to 4-5 stars because they bribed the buyers to change them. My review? Mars ended up getting it deleted after a few months. Just checked the product on Amazon, and there are more 1 star reviews and I bet they will disappear soon enough. I saved all of the email communications and my review.
Anyway, sorry for the long post. I've kept this under my hat for awhile now. I don't like shitting on people buying their stuff. So I don't. But seeing the situation here brought that all back up. Yep, just a fan. But it really brought to light the fact that I will only purchase from companies with great support even if it costs a little more.
