If penny pinching is the main priority, this is a win.  Otherwise.... meh.
Not as well made as the name brand, but that’s expected for the price.  It will probably last half as long, but costs less than half as much, so it’s a net financial win.  But I’m going back to the name brand, Which has an actual elastic strap to maintain tension as you move around at night.  These only fit right when they’re perfectly positioned on your head... it the strap slides up or down even a little, the mask gets loose.
