O Oasis Humidifier for Acoustic Guitars Mandolin

The Oasis Humidifier is a highly recommended product for acoustic guitars and mandolins. Its design makes it easy to use and it is effective in maintaining the humidity level for these instruments, especially in dry climates. The humidifier has clear instructions on how to mount and it comes with a syringe for easy refilling of the bottle, without having to remove it from the case. However, some customers have reported that the fit is not always perfect and that the humidifier is not suitable for soft shell cases with a zipper. There have also been complaints about the salt crystals that come with the humidifier, with some customers feeling that more should be included for the high price of the unit.
