"Thank you so much for the replacement clips. I sent the broken ones back to you with the free postage sticker. The clips work great and this is the first cpap mask I have been able to wear comfortably all night. Thanks Again, Sincerely, Robin"
"These are expensive; however, they do prevent mask leaks of air. Also, they are a barrier between the mask gasket and facial surface, preventing chafing. Sometimes, I can use them at least a second time or third time. They definitely are effective."
