Query: La Crosse WS-9035U

I had great hopes for this product when I ordered it, but, after a little more than 1 month of use my unit is consistently +/- 6 to 10 degrees from actual temperature (figured by cross-checking with other temp sensors in the yard) that is just not accurate enough in my opinion. In addition to the temperature question, the indoor unit "loses" the signal from the outdoor unit at unpredictable and varying times even with fresh batteries and for no apparent reason. This causes the entire "outside" measurements to "blank out" for several hours at a time. The readings always seem to come back eventually, but all in all, for anyone who is more than just casually interested in weather observation, this system is too undependable to be relied upon.
