Peace, mercy, and blessings of God be upon you. I have a respiratory device used during sleep for those who feel shortness of breath while sleeping. The device comes with all its accessories from the VPAP IV company and is in perfect condition, with no defects. The device was purchased from Al-Judei Al-Taqnia company in Riyadh, and the device is like new, having been used for only two weeks. The price is 7500 Saudi Riyals, negotiable within reason.
