I don't think I will buy these again, I will look for a better method of stabilizing my instruments' humidity.

I should stress that I have not had any problems with my guitar, no cracks or anything of that nature, but this system just can't put out enough humidity to keep the guitar safe in a climate with cold winters

It traps the humidity in the container, and the membrane on these packs is two-way, so they absorb it until they reach capacity again.

Taylor recommends 47% relative humidity for storing guitars.

The beauty of these is that the gel packs maintain consistent humidity and make any changes gradually.

I really like the humidpak as it makes keeping my guitar at the correct humidity easy.

Maintains a very stable humidity level.

It is important with this product that when you take your guitar out you close the case, so the packs are not spewing humidity into the open air.

gauges indicate humidity is adequate within case

Maintains proper humidity with virtually no effort on your part.

I'd also tried the theoretically faster Crock Pot technique but that one turned out too problematic, requiring too much effort to keep the right temp and humidity

These take care of everything and keep the instrument at the right humidity.

I also monitor both areas in the case with digital humidistats and I am quite pleased with how stable the humidity remains in the case.

Previous sets last me 6 to 8 months before hardening up and loosing consistent humidity

All in all, they appear to work as advertised and my collection has been that much more "safely protected" humidity wise, giving me the "piece of mind" I would other wise not have

Unfortunately, what I have found is that once the temperature drops below freezing and the humidity along with it, not even double the recommended number of packets will keep humidity in the case above about 35%

and it's working, the humidity is great.

One thing I have done recently is ordered an ultrasonic humidifier which brought the 12 by 12 room where I keep and play my guitars up to the recommended 45 percent humidity in just a few hours.

The ONLY sure fire way to keep your guitar in the perfect humidity range

Keeps my guitar in the perfect humidity and without worries over damage from water or incorrect humidity levels.

I threw in a replacement set which has kept my guitar at a steady 64% humidity which is well above the recommended and advertised level

Since the packets absorb as well as disperse humidity, you basically need to buy a table-top humidifier (another expense) and let it humidify a room or area with the dried-out packets in close proximity

Not only does this let you "set it and forget it", it keeps a consistent humidity level in the case

This will make sure it has the right humidity without a lot of guess work and gadgets.

Just to make sure you have the proper humidity level

This is a great way to easily guarantee that the guitar will be kept at good humidity levels

The relative humidity is 63%+ here (Minnesota fall with AC on).

Working well to keep the correct humidity levels

Otherwise, this is a good humidification control system because it will raise or lower the humidity in a sealed guitar case to appropriate level

Can the low humidity in my heated home be the issue, or are the packets just not lasting as long as previously purchased refill packs

If your guitar is at proper humidity already, then these packs (and the sleeves they go in) do a great job of maintaining the proper moisture levels.

Keeps my guitar in the perfect humidity and without worries over damage from water or incorrect humidity levels.

These are good insurance that my guitar is at proper humidity level, and you can't beat the online price..

The one drawback is having to remember to refill as well as purchasing (it gets a little pricey) the humidity packets

Both products are designed to balance at a suitable humidity

I had a guitar that came from Florida to Arkansas in the wintertime and it didn't like the heating and humidity in my house.

These were highly recommend by the guitar store repair guy to keep guitars in tune and at the proper humidity.

Keeps my case at a nice 60-70% humidity

The product is supposed to regulate the environment within your guitar case and create a healthy humidity level for your instrument

so I'm assuming the wood is staying at the proper humidity.

Besides, here in Santa Barbara, the humidity is probably perfect and I won’t need any humidifier at all

Previous sets last me 6 to 8 months before hardening up and loosing consistent humidity

With the new packs the humidity is just right and the guitar stays i

The humidpaks are a no fuss no muss solution to providing the proper humidity levels in the guitar case for your prized acoustic instrument

For years I did this manually, but with the Planet Waves Humidpak, it keeps my guitars at a constant 45% humidity level "giving and taking humidity", like it is breathing humidity to keep it right without any work on your part..

Where I live the average humidity is 10 percent really bad for my six acoustics

A bonus: they also keep your cigars at just the right humidity

The directions state that you should have your guitar restored to proper humidity levels before actually using the humidification packets, but to be

It adds or subtracts humidity as needed

Works great for keeping the right humidity for my guitar inside the case.

These humidipaks dont seem to last very long in a hot,dry,low humidity desert

As others have mentioned, this is a humidification/dehumidification system, meaning it will add humidity as well as take excess away.

I find they're at their best if you get your instrument to the proper humidity out side of the case and then put these in the case when it's ready to keep it there.

Unlike wet sponge or wet anything systems that you have to check every few days and run under a faucet, this will control the upside and the downside of a guitar's humidity when it is in the case.

A week after replacing the pouches according to directions, the humidity hasn't topped 25%.

Just purchased another couple of "master" bags to hold the replaceable humidity packs, and they're terrible.

Past years, I’ve had no problems maintaining 45-50% humidity in the winter using sound hole wet sponge type D’Addario humidifiers

In the winter I also have a humidifier in the same room running, so the packets work as backup fine tuning the humidity in the guitar case and protecting me whenthe humidifier runs out of water.

Wanted to keep it to the correct humidity level so after reading several reviews decided on this one

If you're attentive to the state of the Humidipak pouches and remember to close your case, they will keep the humidity in your instrument case at a benign level, adding or subtracting humidity as needed

I will say this that for the first 30 days they are at perfect humidity.

I use the Planet Waves Humidipak System to keep the humidity levels perfect in my Taylor 810's guitar case, and I use an Arion Humidifier to keep the humidipaks from drying out

I cannot speak to the ability of the two-way system to maintain proper humidity levels during high humidity summers

The average humidity is now well within the designed range

I've been using this system to maintain proper humidity levels for two Taylor

and humidity should not be an issue

A very good system for maintaining the correct humidity level on your guitar.

Because I maintain that guitar, as well as all my guitars with proper humidity ... the best friend a guitar can have.

if you don't have these i hope you have a room with good humidity
