Query: Inaccurate rain gauge

The Oregon Scientific RGR126 seems to be solid and well-made. Unfortunately, it does not accurately record rainfall. I have gone through two of these now and checked each against a known accurate manual rain gauge; both units significantly under-report the rainfall. To make matters worse the manual calibration feature that this model used to have has been removed, presumably to save money, so there is nothing that can be done about it. I would not buy it again or recommend it.
