I recently switched from the age old sponge type instrument humidifiers to the Oasis. I always felt the sponge type humidifiers dried out a little too fast for my liking. Guess what? The oasis humidifiers are drying out nearly as fast as the sponge type humidifiers.
I think my house is super dry because of the heat pump.
I will say I like the oasis design better because their isn't as much of a worry about water dripping inside of my guitars as with the sponge models.
