Bests & Worsts Reviews from Amazon

I was at my Friends house who bought this exact same filter a few weeks ago and was very impressed. He sent me the amazon link in which he purchased it from and I bought what I though was the same unit. It was the same price he paid, and same advertised model. When I received the unit it did NOT have the digital partial screen in front as many pictures show and as my friends had, it did NOT have the automatic sensor as other units do as well. Thinking maybe I got a bad one I called the company. When I told them my issue I was first told it was built in and automatically senses and the fan speed will ramp up still on it own. I called the guy out because I lite a flame with smoke above the unit and it did nothing when set on setting 1. Then the guy told me to give him a minute to check. When he came back on the phone he then said that these features the unit was missing are no longer offered. As a ethical business owner myself, I find this very unethical and cheating to the consumer. I understand they may have lower margins selling on amazon now but removing features to a unit and not changing the model number or letting consumers know and STILL charging the same price is cheating the consumer. They removed probably about $50 in parts which makes them an additional 10% profit if they are able to trick consumers to buying the “same” product for the same price. I am going to also reach out to amazon about this in hopes others don’t get cheated or in hopes the company makes a new model and lists the features and is clear the old model is discontinued.
