Nasalaire or CPAP-Pro users ???

Has anyone out there used either the Nasalaire or CPAP-Pro masks? I found the regular mask they put on my during my study EXTREMELY claustrophobic, not to mention uncomfortable and I am sure I would not stick with it if I go that route, so I have researched and found these two masks that I thought MAYBE might work for me.

Any input would be so greatly appreciated !!!

Thanks
