In-line Regulator Step DownMany customers want to use the Avi with existing aircraft oxygen systems to increase endurance, but many of these OEM systems output between 70 100PSI. The Aithre Avi pulse demand systems require an input pressure of 50 60PSI, so plugging the AVI directly into this higher pressure source will break the AVI and will cause oxygen leakage. This Mountain High Aithre regulator will step down the pressure from your existing OEM oxygen system from 70 100 PSI

These sandals are gorgeous! The style is sleek and elegant, perfect for both casual and dressy outfits. I was worried they might be uncomfortable, but they’re easier to walk in than I expected and don’t hurt my feet after wearing them for hours. The quality feels great and they definitely look more expensive than they are. Highly recommend if you want a stylish heel that you can actually wear.

Very uncomfortable

Size: 7, Color: Brown Patent

Most uncomfortable shoes I own. The middle part is so hard and digs into your toes making it really painful. I wear a lot of heels and never have I had a pair that hurt this bad.
