Oh my GOD!!!!!!!!!!!!!!!!!! these clips are great. I almost feel like you can use these clips with other things in life other than cpap mask. I kind of wish I bought more of these clips as they can go through them quickly. I like the color is this mask clip and it works great with my Mirage full face mask. My dog chewed through one of these clips leaving me unable to use my cpap mask and it got my angry. I had to show the dog who was boss. These ones are sturdy but like anything else it will break eventually. I like to keep my spares on deck. Don't bother buying this one, get the bigger pack. God Bless One Love
