Query: Nasal Cannula straight, 7ft

The length of the prongs are a relief to the standard short ones, that either flip up or continuously slide out. I am very happy with these and will continue to buy them in the future; I initially bought 4 just in case I would like them. The delivery was faster than I had expected so this is a win-win.
