Replacement Set for F20, includes Most You Need in One Pack, Snug Fit & Great-Value Durable Replacement Supplies by Everness

Fits well and seems to work as well as brand version, but I had to use ResMed magnets for proper functioning. Magnets are weaker which affects users ability to tighten or loosen straps once mask is on. May not seem like a big deal until you are trying to do it at 3AM after waking up with a vacuum leak.

I love the blue fabric around the strap. I wish it had fabric on all straps that touch the face.

I used the named brand version of this for about 6 months. And it worked great. I was a fan of the F10, and the Amazon replacement for that was pretty great. But this one isn’t great. The magnets are very weak, and the Velcro doesn’t hold like the original item.If they swapped magnets and tweaked the design, I might consider it a worthy replacement, but for the time being, stick to the original manufacturer.

Hi by likes the comfort of these straps. He was getting scuffs and scrapes on his neck and head. But it's so much better now.

Definitely stays in place. Good Velcro

Velcro doesn't hold well....

The product was perfect for my machine.
