2021-Jun 7 Anemometer Screw Posts Breaking After 3 years

I've loved the products but the Florida heat is a killer it seems. Today I went to change the failed batteries and found now that two screw posts have deteriorated and just broken and fell apart. Luckily, the two remaining screws are holding good. Maybe some metal posts would be in the future? I would post pics but do not see a way to attach.
