Nicehel Replacement for CPAP/BIPAP Mask Straps ResMed Universal(Gray)

I was hoping for a high quality product. These straps seem to be made with good quality materials, except for one thing, they do not stretch. The straps have no elasticity, so you have to pull them tight enough to prevent leaks and then that's it. I have only had these straps one night and without any stretch, they just aren't comfortable. I will not purchase again.Now after a couple of nights of use I am editing my review down to one star. The straps are narrow and disengage from the upper part of the mask. The lower straps ball up into what looks like a strip of twine and cut into the back of my neck. As I said, at first glance this looks like a quality product. It is not. Do not purchase this piece of junk. I will be asking for a refund.

One side is longer. But I make it work. Thanks
