I have had a system like this from this same company since 2012 and all of it is still working great. I have sensors in both my GTP and BRB that stay higher in humidity. I like this newer version better since it shows all the reading instead of having to scroll through like on mine. I might be upgrading. Also the batteries last forever.
Every Accurite I have bought died in a few months. I don't even recommend them anymore.
