Hi there,
   I have had the WMR-968 for about 3 years nows.    It has basically worked 
flawlessly.   The only real complaint I have is that hygrometer only works 
to -10 C.    Below that temp the RH reading flatlines at whateever it was at 
when the temp hit -10 C.   It stays that way until the temp goes back 
above -10 C.    Turns out that is the operational limit of the unit. 
Problem is up here in Canada the temp can stay below -10 C for weeks in the 
winter.   (Of course once you get much below -10 C relative humidity doesn't 
really mean very much anyway)
     I use Freewx-WI as my weather program and it does a good job of 
compensating for the bad RH reading below -10 C.    It doesn't upload the RH 
to the weather underground, APRS or my weather page  when the temp is 
below -10 C.    No data for a reading is better than bad data!
