I have 2 of them, the best option to have in a big humidor , low maintenance very effective , months to be checked , the only thing I wish they do in future is to make it a bit smaller . work well in big humidors count 200 +
I have this device as it came with my Villa Spa humidor which I use solely for Cuban cigars. It works well and is handy running on battery only power meaning no cable required plus very little requirement for top ups of distilled water for months at a time.
