These guys are the only ones who can send just one part and not make me pay for the entire water less humidifier. Excellent

I have broken two of these adapters. I have owned a Transcend product for over two years. The main mask is built of rigid plastic. I use the product in my travels around the world. I store the mask which has the Transcend Adapter attached. When traveling I put the mask in plastic container and then I put it inside my Transcend Travel bag. I do not think the mask gets beat up in my travels. I believe it is of poor design and is easily broken.
