I found inconsistencies between one reed and another but this seems to be par for the course with reeds generally. Some sound pretty good across all registers. others are a tad unresponsive at the upper or lower ends.. again quite common with almost any kind of reed. The fact that they are sealed seems to give more playing time. The don't tend to become mushy after twenty minutes of playing, which I find can a problem with uncoated cane. Whilst they can sound great and can certainly compete strongly with the much more expensive synthetic reeds I have not found a Plasticover that sounded quite a s good as a first class uncoated cane reed. They probably do, as Rico suggest, last quite a bit longer than uncoated reeds.
