Review on 🎶 The Ultimate Humidikit Bundle: D'Addario Humiditrak + Humidipak - Optimal Care for Your Instruments by Sean Moran

This product is a great concept, but the end product has its drawbacks. Temperature and humidity aren't always the exact readings that really matter, and you'll have to refresh or "flash" the device every time you want to update the information. I put the recommended two packs in the soundhole on top of the strings and one pack in the headstock and was really unimpressed with the two-way humidity control I boasted about. It seems to either overwet or dry out the instrument, but very rarely does it seem balanced. I also don't like how the bags come into contact with the collector's dreadnought paper tag, which can be a downside. I put it in my Martin and it contacts the label directly.
