Guitar Humidifier - Guitto 2-in-1 Humidity Care System for Acoustic Guitar Humidifier Hygrometer 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.

Great design, easy to use, excellent quality

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.

Keep your guitars safe by using this.

I purchased 3 of these humidifiers. I just received the 3rd humidifier today. Out of the box the hydrometer read 50% RH. The actual humidity was/is 24.5% RH. After 3 hours the hydrometer dropped to 40% RH and has remained at this level ever since. The other two humidifiers I purchased have their hydrometers locked at 50% RH. The dial never changes. The way one must fill the humidifier with water is ridiculous. DO NOT BUY THIS HUMIDIFIER ITS JUNK!!!

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.

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.

I live in a dry in winter climate so I need to protect my Martin from drying out in winter months. This unit is easy to use - it comes with a little bottle to add distilled water periodically and the humidity gauge assures that the guitar is safe from drying out.

Good bargain, bought 2

Excelente producto

Me gustó el precio y lo funcional que es.

am not sure how accurate the unit is but it is nice to be able to see that the humidity level is within the correct ranges to preserve the wood on my Taylor

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.
