Jim DunlopHerco Guardfather HE360 Guitar Case Humidifier

Seriously useful in the recent heatwave. Kept my lutes save in very very dry conditions.

Great price! The concept of placing the dampened and sealed humidifier within the guitar case means there is no leakage inside of the instrument.

I have used these humidifiers for years in my guitar cases. They work well anbd seem to last longer than sponge based systems. Also not bad for the money in truth.

Surprisingly good job (after widening holes) of humidifying my old dreadnaught.

For the price size I thought this was a gimmick ,However,I should have known that Jim Dunlop products"does what it says on the tin",Handy and very useful.

Compact size and seems like it should work fine. Speedy delivery and a good price.

To be honest,my guitar seems to be fine but was fine anyway. I think the action and tuning seem to be a bit more under control since I started using it. It seems to soak up a fair bit of water and needs topped up regularly,so it must be doing something!Thought I'd try it out and I think its a keeper.

I bought a couple of these in the USA. I appreciate their compactness and the low risk of leakage. I tested mine with a hydrometer. The relative humidity inside the case was six percentage points higher than in the room. So it works, but if the indoor humidity were down in the 20s you would want something stronger.

There is not much to say about these little things. They are inexpensive ($4 on Amazon) and they WORK! This is basically a sponge (actually it's clay) in a little can, that keeps containers or guitars in their cases from drying out. You fill it with water and set it in your case or container. It does not spill or drip. You can't adjust the amount of humidity, or how fast or slow it humidifies the space like some more expensive products, but then in many cases that is not needed. If you're a cigar aficionado and need to keep your precious Cubans exactly 72% humidity, this is not for you. If you have some herbs or a musical instrument you just want to keep from getting to dry, this is the ticket. I will buy more of these. Depending on the humidity of where you are, it usually last around 2 weeks before having to refill. If kept in a small container or jar with herbs for example, it will last 3 or 4 weeks.

It is a pot of clay that slowly vents off its humidity after being 'watered'. Pretty lo tech but works way better than other methods and can keep humidity in your closed guitar case for over a week even in a dry environment. Same principle as clay disks used to keep brown sugar / molasses flexible in the jar - ask your grandmother.

excellent produit pour protèger nos guitares

Ho acquistato questo prodotto perchè consigliato da un amico, prima non ne conoscevo l'esistenza. Contrariamente ad altri prodotti simili non si mette all'interno della chitarra, ma nella custodia ( molto meglio). Il funzionamento è semplice: basta tenere inumidita la pietra che c'è all'interno; quando si asciuga si ripete l'operazione. Io ho una Ramirez: sulle istruzioni ( ho controllato dopo) è caldamente consigliato l'uso di questi umidificatori. Tutti quelli che hanno uno strumento in legno dovrebbero usarlo.

And it works like it is supposed to. Nice in that it can't spill unless you really do something wrong. Definitely an essential accessory for acoustic guitars in dry environments.
