This is lightweight and keeps my face visible and my ears exposed - I can use my stethoscope, hear soft voices and see very well. I am a mobile physician and spend the day in the T-200..
After about 50 hours of use the 2 parts that click together lost their snap and the pieces would not stay together; the integrity of the system was compromised. To get through the day I upped the airspeed, which worked. Later I wired the pieces together to restore function. I have used T-200 assembly and drape for over 100 hours now - the headpiece is so comfortable I have forgotten I had it on site.

When traveling with the headpiece, there are several problems. I find that the location of the air hose prevents me from using a headrest. When I sit in a car or plane seat, the hose pushes my head forward and prohibits head support for long or rough travel. The T-200 has excellent visibility- but I cannot drive with the using the T-200 assembly because of the hose location prevents a full sit back in the seat. RPB is good about improvements - I hope they will advance the T-200.
