I bought this unit to replace an Oregon Scientific unit which I really liked, but it finally died after about 5 years and is no longer available. From the start this unit was trouble. It would not transmit anywhere near the published distance. When I would get it to work, it would work for awhile, then lose reception. I finally located it about 20 ft from the receiver. Accuracy is very poor. It is lucky to measure half the rainfall compared to a manual rainfall gauge. Also, you frequently have to clean spiders out of it. It finally quit working after 8 months. (Yes the batteries are fresh and the spiders are cleaned out.) I get 0.00 but it will not measure. I have considered sending it in under the warranty, but since I don't like it anyway, why waste the postage? I think it is going to end up in the recycling bin with other electronic trash.
