The thing I was talking about bobalouie,is similar to your's.In fact it's made by the same company.ClimaGuard from Cigar Savor.Its the red stick filled with some type of foam with beads in it sitting on a spring.When wet the thing weighs down the spring hideing the red sticker in the window.When dry it raises up displaying the red sticker for notice of a refill.
It handles more cigars then the other thing.I only have one for a hundred and my humi stays 67-69%rh all the time.

I just ordered 2 more though.
