Some good, some bad.
I don't care to be badgered about what I need and don't need. I take very good care of my CPAP and supplies. If there is something I think should be replaced or that truly needs to be replaced I ask if it is eligible. I don't really care to be questioned or given a "sales" pitch. The representatives are usually very pleasant and helpful, but the last two times I got "attitude" when I didn't order just what they were trying to sell me.
