    After playing for around 40 years I finally committed and bought my first premium acoustic guitar. A sunburst Martin d18. I obviously wanted to maintain it at the proper humidity to ensure the safety of my new "baby". Doing some research and asking friends who play and have premium instruments I settled on the Humidipaks. After approximately three months after first installing the Humidipaks my guitar case has stayed consistently at the optimum humidity levels. Every time I check the humidity it is just where it should be and the packs are still soft and usable. I live in New England and so the humidity and temperature is going to change wildly throughout the year but even with electric heat in my house the guitar case stayed at the desired humidity. I couldn't reccommend this product more highly. If you have a good guitar, a guitar you love, get this product and rest easy knowing your instrument is safe and being maintained properly.

    No matter where you live, your guitar(s) need to be treated with respect. You shouldn’t leave them exposed to significant changes in temperature and humidity. Don’t leave your guitar in your car/truck/van unless you’re headed to a gig, jam session, or lesson! Don’t leave your guitar leaning against a wall or furniture when you’re not holding it - use a proper guitar stand for TEMPORARY breaks in the music. Storing your guitar in its case, when not practicing/performing, will help protect your beloved axe. (NOTE: Keep your guitar’s hard case closed all the time, except when removing the guitar or storing it after practice, etc.)

    Controlling the environment in your guitar’s case is IMPORTANT, too! A hard case is best because it can also be easier to control the atmosphere your guitar lives in.

    I use these humidity (restoration or maintenance) packs all the time in my guitar hard cases. I live in the subtropical Gulf Coast region of SE Texas.

    You might ask, “Why do you put humidification products in your guitar cases when you live in a humid environment? That doesn’t make sense and it sounds like a waste of money.”

    It DOES sound squirrelly, doesn’t it?

    Well, this product works TWO (2) WAYS to maintain the correct humidity level for your guitar! It can release OR absorb moisture inside your guitar hard case, keeping the headstock, neck, fretboard, top, bottom, and sides at optimal humidification.

    How often you have to replace the packs depends upon the climate and weather your guitar lives/works in and how you store it. Taking care of all that wood (and don’t forget the electrical components if your axe has ‘em) by preventing or mitigating cracks, swelling, joints and glued parts separating, etc., will help extend the life of your guitar and keep the coveted sustain and resonance going.

    Great product! I will continue using this company’s humidification products, for as long as I have guitars to take care of, so I can enjoy fingerpicking, strumming, and shredding.

    5.0 out of 5 stars A reliable, low-maintenance solution for guitar care!

    The D'Addario Accessories Guitar Humidifier Maintain kit is a simple-to-use, effective solution to protecting your guitar from damage due to low humidity. The simple device fits inside the soundhole of your guitar and releases moisture evenly to keep the humidity at an optimum level. Especially good for acoustic guitars and wood instruments, it helps prevent cracking, warping, checking, and dry wood conditions. It's really easy to use. Guitar owners will rest easy knowing their guitars are protected.

    5.0 out of 5 stars They don't tell you these are rechargeable (or for ukes), but they are
    Reviewed in the United States on March 6, 2013
    This is a GREAT product (that could just benefit from somewhat better directions)! I use them with both guitars (essentially as intended) and my solid wood tenor ukulele. For the uke, with its smaller soundhole, I slip one of the cloth bags that holds a single Humidipak (designed to lay in a case under an instument's neck) between the 4 strings and the soundhole. I don't actually try to cram the guitar-hole-sized Humidipak into the uke's little soundhole, as that's neither necessary nor prudent, given that Humidipaks harden as their moisture becomes depleted --which might make it difficult to get a dried out Humidipak out. I love that these things are fairly foolproof, as I didn't like the idea of potentially damaging my solid wood Martin guitar by water dripped from a competing product. The main criticisms I've seen of these are (1) price and (2) length of use before disposal. But the online pricing is quite good, especially factoring in the fact that these are RECHARGEABLE not just disposeable. They balance humidity, right? So when they dry out, simply temporarily store them in a humid environment and... voila, good as new! My first attempt at this worked wonderfully: (1) partly fill the bottom of a relatively large, air-tight food storage container with tap water; (2) place a relatively heavy but smaller container such as a stoneware bowl that won't float in the water; (3) place some (I did 3 at a time) dried out Humidipaks in the stoneware bowl (rather than throwing them away and buying new ones); (4) close the air-tight lid on the large food storage container; and (5) wait until the Humidipaks become soft and fluid (like new) again! So perhaps buy some replacement Humidipaks so that you can be recharging some old dry ones while other moist ones are slowly discharging in your instrument case(s). That's what I'm doing, and thus far I'm 100% satisfied with the ONE-TIME up-front purchase costs (assuming I can recharge these indefinitely?). Furthermore, for the rare few who live in overly humid environments, you could use these as DE-humidifiers. Just don't make the mistake some have made in thinking that you can benefit from placing a fully moist new Humidipak in your instrument case to absorb excess moisture. First somehow DRY OUT some Humidipaks and then place the hard, dry Humidipaks (that many would throw away as trash) in your instrument case to absorb the excess moisture. Repeat as necessary...
