They did a free dinner seminar. I went the presentation was very convincing. They offer free inspection next day so I bought in to the crap. The presentation was miss leading saying the probiotic system will help with allergies breathing problems clean the air. It’s crap my wife allergies never went a way and we changed the air filters as well. It’s a bunch of crap and I got suckerd in to it. Now I got a 53 dollar a month payment on something that doesn’t work. 3500 piece of junk. I want a refund. Fraud!!!
