Just awful service! Uncaring and unhelpful! Online ordering is difficult and I had to call them and then stay on hold much too long to get help. Then they sent out a new machine with the wrong settings and now tell me that I'll have to reset it myself. This is an expensive BiPap machine and they should have cared enough about the sale to get it right! I also have an older machine from them that I've never been able to use. Anyplace that was the least bit professional would have confirmed the settings before shipping this new machine to me. Also, I did some research and learned that the range of settings is different from what they told me.
