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

So far this has held up great. My Malinois who has destroyed nearly every ball I’ve gotten her, this one has lasted over 3 weeks without a dent, compared to some that don’t even last a day lol. Although the medium size is a little too big for her liking she still plays with it. It’s very durable and I like the middle part for engagement as well. I would recommend if you have a dog who destroys every ball possible.

Actually Durable

Color: B) Medium 3" Ball

One of the few "heavy duty" toys that my pittie hasn't destroyed after a couple of weeks. Most of them last two days. She's an absolute beast so I'm confident if she can't destroy it, few dogs can.

Not for aggressive chewers!

Color: H) Infinity Ring, Color: H) Infinity Ring

Not for aggressive chewers! Done for in about two minutes. I unboxed this and tugged with my Mal for a but then let her have it. Within minutes she had chewed through it. Not worth the money.
