    Although I've invested in the D'addario 2 Way Humidipak system, which adds and removes humidity for the Guitar in its case environment. Having the D'addario Humidifier and Temperature Sensor in the case just gives me that extra piece of mind. Programmable humidity set point and a memory function that you can check for any high or low readings during a set time. This is because it has a clock and date function too. A little bit pricey but if you love your Guitar or string instrument. If it's valuable and so on I believe it's worth investing a bit. Should last a long time. All needed are occasional new batteries.
