The good thing is that the humidity will reach the neck since it is not enclosed in the body like other humidifiers

For the price, this thing has really given me a benefit.

...and this thing makes the tone of my guitar so much richer by keeping the wood moist.

The nice thing about it is because it doesn't seal up the soundhole on your guitar it will humidify the rest of the instrument when kept in the case

Love this thing

This item is not bad for the price, but the two things I don't like are first that you have to push this thing down into your strings and it forces them apart (probably not a big deal, but I don't dig it).
