D'Addario Humidipak Guitar Restore Kit, Two-Way Case Humidity Control

Nice kit. comes with pouch and humidifier pack. place the pouch with a pack inside and put around the instrument neck. works for months. Easier to use than the things you need to fill constantly with distilled water.

Worked beautifully.

This is a must have to keep your guitars in top shape trust me been playing 40 years, need one in every case I change mine every 2 months ..

The review title is the main point and covers the important stuff. I had a number of wood acoustic instruments in Houston Tx in a house that between Summer AC and Winter Heat averaged 40-60% humidity (i.e. in the recommended "range") with occasional extremes down to 38% which I felt my guitars and ukes etc. could handle. After 10+ yrs I noticed some low humidity issues so I got got a few of these and starting with 3 acoustic guitars I started the process of re-humidifying cases and guitars. I bought 5 relatively cheap hygrometers to put in with the instruments. After 3 weeks all were showing ~60% in their cases. I had to add some standard water based Oasis humidifiers due to the packs in this product starting to dry out before the 3 weeks was up. This worked and kept them at the 59% humidity. Hence 2 stars for longevity. When I got everything where I wanted them I added water based to the sound holes as they hang on the walls with the hygrometers. I am a little disappointed in the varied instruments them selves but it's really about Houston. Our house literally runs 38% up to low 60% and the acoustics cannot keep up. Unfortunately, with them in their cases, I do not just pick them up and play as much.

Brought my guitar back to life after it dried out. The Humidipak system is set-and-forget easy, and my guitar sounds and plays so much better now.

Works great

Living in a dry climate like Colorado, I was really hoping this humidifier kit would help protect my guitar. While the system itself is very easy to set up, I was quite surprised to find that the packets became completely hard after just about a week. Because they dried out so quickly, it’s honestly a bit hard to tell if there was enough time for my guitar to actually absorb the moisture or if there's been any noticeable improvement in the wood. It seems like a decent product overall, and I imagine it lasts much longer in areas with moderate humidity. However, if you live somewhere exceptionally dry, just keep in mind that you might go through the refills very fast.

The best solution I have found for protecting my acoustic guitar. No filling up a reservoir, and even in the AZ desert it did its job. You can tell when you need a replacement - the bag gets stiff. Easy to use.

Must have in your guitar Case

Largely restored the fret sprout on my Lowden acoustic. Would buy again.

Compré este paquete de D'Addario, lo coloqué en la guitarra como pone en las instrucciones y cerré la funda. Ha pasado casi una semana y el hidrómetro que coloqué dentro de la funda marca siempre 61 o 62%. No sé si es que estoy usando el producto mal o que me tocó uno defectuoso, pero a mí no me está funcionando

Excelente producto me sorprendió, en un par de días alcanzó la humedad al 45-47%, y así se ha mantenido por 4 semanas. Sumamente recomendable
