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

The Good: Well Designed: Sturdy and aesthetically pleasing. Effective: Perfectly obstructs the afternoon sun glare from my monitor screens. Moderate Assembly: Straightforward and easy for the most part. The Bad: Defective Part: One crossbar end was missing threads, preventing the assembly of the sixth panel. Zero Communication: I emailed the seller as instructed and waited 8 days with no acknowledgment. Return Logistics: Amazon offered a return, but the box is heavy, and disassembly/repackaging would be a major task. Final Verdict I really like this product, but I’m deducting two stars for a total lack of customer service. I’ve decided to buy tools and fix it myself rather than deal with a heavy return. I hope the seller sees this and reaches out. The lesson learned is to check every part of a product before assembly.

Clean Look, Sturdy — can’t ask for more!

Really like how it folds so I can create kind of a doorway with two of these. Pretty easy to assemble and has an uncluttered clean look due to the smooth fabric and nice color. Oh and it’s sturdy enough for pets.

Lovely, but lightweight

Attractive and does what I needed, but is very lightweight, so must be secured.

Good quality product

Attractive and sturdy! Only draw back are the small gaps in between the weave. Not large ones but they are present. I live in Chicago and it has held up nicely with the weather.
