This product does not do it's job and it isn't a proper swivel elbow. The purpose of the elbow is to remove strain and stress from both the tube and mask during use, as well as provide unrestricted inhalation without leaking pressure. This product does none of this.It does not swivel, putting strain on the hose and causing partial mask leakage. It also doesn't hold a proper seal, causing the machine to read erroneous data. The non restrictive valve doesn't even work at pressures below 15PSI, leaking all the pressure through the intake ports, causing the machine to stop thinking it's no longer in use. The valve ports also cause restricted airflow from the CPAP, causing it to push higher pressures than the user might be comfortable to. The bleed ports around the edge of the quick connect can whistle at high frequencies and may hurt some users ears.The only good thing going for this product is the frosted plastic looks really nice.I should also note, I got the same results from both elbows. This isn't a defective product, this is a design issue.

Great item, helps with mask leaks

I had significant masks leaks with this replacement elbow. Because it only swivels side to side. It does not move up and down like OEM.Which cause the mask to not stay sealed against face.

Was a great fix to getting my CPAP machine to work correctly again. My previous nose mask was better then 6 months old.

Cheap, but... cheap. They leak 10 times as much air as ResMed's factory ones do. The leak is loud. I tried tying a cloth around the connection but it doesn't help much. The clips wear out and it starts falling off the mask.

Fit perfectly, no noise or leakage
