-This strap will relief the tension on the neck, because the strap rests on the shoulder.
-The strap can be adjusted in length with one-hand action, shorten it with a simple tug or lengthen it with a relief on the buckle.
-The metal hook is fully closed by spring action giving security with your every move.
-The padded shoulder parts makes the strap very comfortable to wear, even for longer periods of time.
Cons (minor issues though, more reflections):
-It takes a bit of time to get used to this (or any) shoulder strap, because it positions the saxophone different to the body (more to your side). Which is perfect for bigger saxophones like tenor, but less perfect for alto.
-The buckle is pure metal which gives it strength and durabilaty, but might damage the laquer on the saxophone support ring. (Adding some tape ore a rubber sleeve around the hook easily prevents this)
Overall it is a very durable, comfortable strap with great value for the money. I strongly advise it.
