Product review (5 stars): Keeps Reeds in "ready to go" condition.
Purchased this case for my son. He plays alto sax. We live in Arizona where the humidity can get down to as low as 2% which can dry out, warp and damage reeds. During the Monsoon season it can get really humid.  We have both extremes here, but mostly low humidity.

The case comes with a 73% RH packet which is keeping his reeds in "nearly" ready to play condition. Places the reed in his lips for a few seconds and he is ready to go. Currently he is using Rico Royal reeds.

Its a well made case and you can use the case without the humidity control pack and it fits inside the storage compartment inside his instrument case.

Its about half the price on Amazon compared to local music stores ($22 - $28).
