Hello by mistake unscrewed the rain gauge screws and now my rainfall is not correct. Iam so upset!! At this point its still under warranty and iam not putting the 5-1 on my roof again risking falling until 100 precent sure its working properly. I'd like to exchange the unit for the same one the only thing I can't return is the mounting bracket cause its nailed to the roof bigtime and I don't have right tools to remove. Iam very depressed by this I put lots of money and time into station. Iam ready to ship back hopefully for a new replacement. This was a gift for my son hopefully accurite will exchange for same model. my email is email@example.com if you want to contact me. Ive already tried to calibrate with cup but just don't feel confident doing it right for my son so my reason for a new one. Hope to here from someone soon. Edit..It was also having issues with temparatures so at this point I would really want to exchange this for an identical unit its the model number (06014RM) its brand new just 2-3 months old.. Hope this process is quick I feel really bad for my boy.
