The system seems to work fine but the bag in which the humidipaks are to be placed is too large. I have a full sized guitar (not jumbo) and the packs still touch the bottom + the width exceeds the sound hole so it is difficult to actually hang it. Other than that these seem to work fine. For people who are in dry places the problem of these running out soon can be solved using a home-made humidifier ( can be anything, wet foam in a small box with holes or even a wet cloth placed in plastic/polythene bag). Place both in an airtight container (without touching each other) and the humidipacks will absorb extra moisture coming from your home-made one and will, effectively get refilled and will last longer. Also, for effective usage on really dry guitars, covering the sound hole with some impenetrable sheet will make the humidification process faster. The only downside is the size of the pouch given to place the humidipacks.
