I've had this for about 4 months, I use it about 2-4 times a week so that isn't that much, right? A couple of nights ago, my nose itched, so I reached up to push the lever and the plastic door fell into the hole, air was loudly blowing into the room. I shut off the CPAP machine, took off the EZ Talk, connected the hose to my mask and went back to sleep. The next day, I examined it closely, I thought it was broke, but it wasn't. There is a thin metal pin that is held in place by soft material (the same type of material that my mask is made of- possibly vinyl). The pin slid to one side and it was what held the door in place, once it slid to the side, the plastic door fell off. What scares me to death, is if this pin had dislodged, I am not sure that it couldn't or wouldn't have traveled right into my nose. There was nothing to stop it that I could see, it was small enough, and then what, right down into my lung? Well I put it back together, and used my laser glue, to glue the ends of the pin so it won't move again. The plastic door still works perfectly, and if it wasn't for this movable pin, I would have given it 5 stars. Because rather than turn off the CPAP, I like how this product works to scratch my nose or talk to my husband. I then washed it in warm water and white vinegar, rinsed, then washed it with Dawn detergent and warm water, rinsed in cold water and dried thoroughly before attaching it back between my hose and mask. The pin, hopefully, will never slide again, but I will be checking it weekly to be sure it is still secure. And I have a backup EZ Talk, I'm going to attach a note to the unopened package to laser glue it before the first use. I know you'd think I'd never forget a scare like this, but who knows it might be years before I open that package & my memory isn't improving with age.
