Query: Don't throw away your direction booklet!!!

I understood that this was to be the best product becuase it was digital and crystal clear. When mine worked it was clear, but the problem I had was that the partent unit and the base unit would constantly loose connection with one another. This would happen nearly everday. I would reset the units just as the directions said, it would work for awhile and then loose connection again. The combination to reset the units was also confusing. Try reseting at 3am. I went back to the cheaper monitors because I hear everything just as good and I don't have to worry about loosing connection at 3am and not hearing my baby.
