Compared to the competition, even the "old" design was only marginally effective; the sponge inside that holds the moisture was barely big enough to do the job.

I like this design better because of one simple fact.

Excellent product, simple and practical design,holds firmly inside the guitar mouth and keeps humidity levels in the safe zone

Simple design, easy to use.

I like the design and ease of use, that's why I gave two stars instead of one

This is a much better design for two reasons

This is a really awful design

This humidifier is not a good design

The new design makes them much easier to use than when you had to inject the water into the device with a syringe.

Love it, thank s!
