I made the mistake of buying a wifi camera from this company. The software they want you to use (Tuya) is poor: it doesn't link well on our wifi (another company's camera/app combo we have used is much more dependable), it was finicky to set up (the other company's app was much easier), it doesn't uninstall easily from iPhone, and they make you PAY for push notifications (the other brand's software included that free).
I asked for a refund (less a 15% restocking fee, which, frankly, I understand). Instead of an RMA, I got a reply asking what the problem was. I told them their software is poor and their equipment, while nicely built, is overpriced.
They advertise "hassle free returns"! That IS NOT what I'm getting!
They told me tech support would contact me within one day. That's not what I asked for! I just want 85% percent of my money back! I guess I'm just gonna throw it in the trash and count it as a $339 lesson!
UPDATE 11/18/22: Two days after I posted this review, Zetronix sent me an RMA number. I had also sent them an email telling them that I didn't want support, I wanted 85% of my money back.
I'm returning the product. I'll see how it all goes.
