It's perfect!

It's perfect. It's the one I started my CPAP and now BIPAP experience with more than 15 years ago. My DME suppliers of recent years would send only generic straps and I finally stopped asking for them and used my old ones. Of course, the old ones became a little stretched out over time but were still superior to the generic ones. Now I have three new ones. Thank you for a good product.
