  • ใ€NOTEใ€‘The daily rain deviation of WS90 is very small in the long run, but under certain conditions the deviation could be larger: As the rain drop size and wind speed can have different impacts on the sensor output which lead to this variance. The WS90 product suffer from this imperfectness. If you are very demanding on rain data accuracy, we recommend you purchase WH40 and use it with WS90. If there is no precise requirement on data of each rain, then WS90 is just fine.
  • The heater on the WS80/WS90 is only suitable for the ultrasonic reflection surface. It will not melt snow that has built up on top of the device.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
