I bought a Resmed AirSense 10 Auto CPAP and a mask which 1800CPAP shipped to Japan. The shipping was via FedEx and very quick, customer service including communication was excellent. Items were well packed as well. My friend(he recommended 1800CPAP to me) also purchased a mask and had it shipped to Japan quickly without any issues.
Based on my experience I will be using 1800CPAP again.
