This mask replaced a "Three Window Mask" which I had for about 15 years. The plastic "loop" through which the strap went broke and couldn't be repaired. Otherwise, other than having "yellowed" with age, there was nothing wrong with it.

This Dynasty Mask will probably never see the wear and tear that the old one did as I am in my late 70s and most likely won't do anymore scuba diving. My use will probably be limited to my almost daily year round lap swimming here in southern Arizona. I swim with a mask and snorkel as I have limited side to side motion in my neck and I can do 3/8 to 1/2 mile with my face in the water.

The new mask is lighter than the old 3 window mask and not as bulky. However, it isn't as soft and comfortable around my upper lip as the old one. I don't know whether it's because the rubber is stiffer or because the frame of the mask is plastic whereas the old one was clear rubber. However, it is fine for what I am using it for.
