2) Straps are too narrow and slippery causing magnets to slide off.
3) Cushion frequently falls out of nose piece. Nubs should be larger.
4) Design causes excessive pressure on the back of my head just above neck creating a headache.
Thus, this is not a product I recommend. I went back to my Mirage Activa LT which I find barely acceptable. The manufacturer made major modifications in this headgear without changing any of the product numbers, so it might be unpredictable regarding what you'll get when you order.
