Having read through the responses here regarding this number, it is a mixed bag of information. Like the others, the person on the phone was quite polite and obviously had some information about me. Since we sometimes do surveys, and who can remember everything all the time, I stayed a bit longer on the call. The red flag was the amount of the "gift". Not interested in a demonstration or anyone coming into my home, so that was not going to happen. What I find interesting is the first few posts at the beginning were glowing reviews with purchases of the machine. They fail to mention the receiving of the gift or what the gift was. If I received a $300 gift and everything was legit it would definitely be in my post about the company. Are they legit? Can't say. Better Business Bureau has people who love it or who hate the sales tactics of the free gift carrot to get in the door. There is a website for zephyrairsystems.com, so they seem to operate in the different provinces under different names - Coast Medical Air in BC. Phone number that called did not match contact details on the site. So could go either way, but not something I want to be involved in. From what I could piece together, it's a real company that may not be using the best sales tactics to get sales.
