Product review (5 stars): Does What You Want It To Do!
This is an extremely good product.  The vitalizer packs keep my reeds at exactly the right moisture level for playing.  I can take them right out of the reed storage case and play; there is no need for soaking the reed in my mouth for a few minutes.  One caution:  The packs last pretty well after being removed from their protective package and put into the reed storage case, but they must be replaced when the fluid in them hardens into large grains.  The more the case is opened, the faster this happens.  A very good and useful product!  I will buy these packs often from now on.
