Negative Positive
Title: not as effective as stated
Review: I found this humidifier to be ineffective, at best keeping my guitar at 35% (I have a hygrometer in my guitar case); not much better than the humidity level in the rest of my house. I bought a kyser at the same time for my classical guitar, which worked much better; throwing away this one and buying a kyser for my acoustic guitar.
Is the review positive or negative?
