Query: nice and easy to read but wish it had a back cover to protect the coils

We keep this thermometer+hygrometer at our back porch. it is only hung with one nail on the top and the bottom is touching the mesh-screen which makes the hydrometer coil touch the screen. makes me wonder if it reads correctly but I believe it does. Like other reviewers said, it does what it's supposed to do: tell temperature (accurately) and humidity. Very easy to read. Just wish it had a back cover.
