    I really like this mask because it's higher flow rate allows me to stay in 02- longer

    Although I just received my new ultimate Ewok mask kit, and have only used it once; nevertheless, I feel confident in saying that this mask is a major improvement compared to the neoprene and silicone mask kits. One drawback I noticed right out the gate, however, is the lack of written instructions pertaining to the headgear that hold the mask in place. What is included in this regard is the same photo found on the live 02 website of the gal wearing the new mask, and a photo of how the Velcro is used to shorten or lengthen. The second photo is unnecessary I think, because the straps come preassembled using the Velcro. If you study the first photo very carefully, most of the "how to" is intuitively obvious. Difficulties can arise, as they did for me, since I was anxious to use the new mask, and all by my lonesome to make it work. For example, the headgear is slick and red on one side, and fluffy beige to hold the Velcro on the other. For some reason, I thought the red side should be on the outside. It is not. The first clue is the way the straps must be twisted to be used when the headgear is upside down. The red side is the proper side to come in contact with the face and head. Another problem, which I have only partially resolved, is how loose of the black buttons are when inserted into the four receptacles located on the outside of the mask. They do not snap, but are only held in place via strap tension. Getting the straps to the proper length and then using them probably isn't a problem for two people -- for one person, not so easy. I wound up using tape to keep the black buttons from slipping out on one side of the mask, before pulling the straps behind the head and neck to be attached on the other side. One final point. One of the straps is actually two straps joined together. My initial thought was that this strap should go on top. Although not that obvious, the photo of the gal wearing the mask suggests that once again I have things backwards. Oh dear! Hope this helps. Maybe I'll put a video on YouTube. I have a hunch once a person has some experience, he or she could hold the mask on your face and put pressure on the black button fastener with one hand while positioning the top strap. With the mask now sitting on your face, the bottom strap should be a slice of cake.
