Product review (5 stars): this tracker is great for him to be able to monitor the humidity ...
My husband bought this for his safe and so far it is working really well! Since we live in a very humid area, this tracker is great for him to be able to monitor the humidity levels in the safe without opening the safe over and over. We have rechargeable dehumidifiers in there as well so this allows us to see when they are running low and need to go on the chargers. Great product for our needs.
