The unit was exactly what I was looking for and at a great price. I sent my prescription so that the unit's pressure could be set (and I was assured that it would be). Somehow this was overlooked and didn't happen. I need to get this programmed and have yet to hear a response. I guess there is such a thing as "shipped too fast".
I was quoted $3000 to purchase the same machine from our local supplier. I purchased the same for $800, from cpcp supply and found it was easy to set up. Utube helped with out of normal settings.
I find this system robust and long lasting and it suits my nose breathing needs well.
