GUITTO 2-in-1 Guitar Humidifier & Analog Hygrometer, Clip-On Soundhole Humidity Care System with Refillable Sponge, No-Battery Gauge for Acoustic Guitar (GHD-01)

I humidified my Martin D-35 but never knew if I was over doing it. Now I know. this thing tells me. And if it's dry, it'll humidify as well.

Nice gauge

This humidifier works fine for what it is designed for. It fits fine on my guitar and does seem to help with hydration. My only complaint with this is that it does seem to dry out very quickly, and injecting liquid into it can be a little bit challenging until you get the hang of it. Good value for the money.

Stays in the case and apparently tells me when my instrument is dry.

I had a feeling that this might not work well but was lured by the pretty hydrometer, which is probably the main problem. Most guitar humidifiers are designed to work for a guitar that's in the guitar case - a closed environment that keeps in the humidity. In the open air, humidifiers don't have much of a chance of working. With this device the guitar case lid won't close without putting a lot of pressure on the hydrometer dial and therefore on the top of the guitar at the sound hole. In fact, in one try, the lid actually pushed the humidifier into my guitar. It would be best to avoid this humidifier and buy something with an established reputation for working. Then, separately, purchase a small, inexpensive hydrometer (they come in six packs on this site) to monitor the humidity in your guitar case. I'm glad the Guitto device was only $13 US and I'll probably keep it just to look at...

I have to wonder whether the folks who say this is easy to use have used any of the other drop-in humidifiers like the GuitarNomad or the D’Addario. With those, you wet the “sponge” by removing it from its holder and soaking it in distilled water, maybe squeezing a tiny bit out, put it back in the holder and drop it in between the strings. This thing has a little bottle with a needle-like outlet that you fill with assumably 5 ml of (unspecified, but I use filtered or distilled) water, twice. Once in each fill hole. Why? Do the fill holes lead to different places? What if you forget which one you did first? What happens when the sponge gets funky, if you can’t open the holder to replace the sponge? I much prefer the ones that you just open up and resoak, as I described. Some have said that the hygrometer is not accurate. I have nothing to test it against but it said that my apartment was pretty dry at under 30%, so as long as it goes up from there, I’ll assume that it’s helping, and I don’t need a gauge in all the instruments if I have one that’s working. We shall see. Nice build, looks good and professional. I just think that the whole filling routine is a completely unnecessary pain in the neck.

Its cool

Easy to use and read. I have purchased a second one for my other guitar. I like them size as it fits the guitar well and causes no damage. It gives me an easy way to read the humidity level in the case. It also is easy to add water because of the dispenser that came with it. Well made, easy to read, highly recommend it to anyone wanting to protect their guitar. I have one for my Yairi 6 string and one for my Alvarez 12 string.

Good bargain, bought 2

Aparentemente si funciona que es lo mejor dado que estas cosas chinas comúnmente fallan. No lo he necesitado probar como humidificador porque donde vivo es al revés. Se necesita quitarle humedad pero bueno. Si parece funcionar

Excelente producto

Looks good but unfortunately doesn’t fit in ovation guitar hole. Utilized in other guitar

Me gusto que se ve bien construido, es un poco grande para mi guitarra clásica y debo mover la cuerda para meterlo. El higrometro funciona aunque no se que tan exacto sea porque no tengo otro con el cual compararlo, se que funciona porque se mueve. Pasando a sí funciona, si funciona mi guitarra tenia problemas de resequedad lo puse y al siguiente día la madera había cambiado de color y sonaba mejor.
