This reed is immediately ready for service and is easy to use. I like the sound. It doesn't get soft after lengthy use of more than an hour. I now have two of different strengths which I use on two different mouthpieces.
The only sensitive point is their storage. Legere recommends not keeping them in the original packaging but these reeds are very thin and are not retained well in most of my reed cases. Following my query, Legere recommended the Protec reed case which I bought. Although it gives complete satisfaction in most respects, these Signature reeds are still a little thin to be held firmly even in the Protec case.
I have also bought a Legere Quebec cut reed which is thicker. For me it performs just as well and holds better in the reed case.
