New Humidifier Day! After much research, hand wringing and trepidation I bought one. I keep all my guitars in a very small room (8x8) and was tired of filling soundhole sponges etc. Took them all out of their cases, 4 acoustics 1 classical and 7 electrics and placed them about the room, some on hangers. Then set the humidifier to 45% and life is good I hope. I bought the below listed model based on 1 main criteria and several lessor ones. 1) I can set the amount of humidity in 5% increments and it only runs until the room is up to the desired setting then shuts off. 2) Shuts off automatically when out of water. 3) Easy to clean 4) Type (Ultra Sonic) 5) Cost < $60.00 It was recommended on a couple of guitar sites for small room humidification. In all fairness there were a couple of others as well but this one had what I was looking for in features.
