Query: Save your receipt.......you're gonna need it!

All I can say is keep your receipt. The wireless rain guage is a piece of garbage. Apparently made in china. I had mine set up for almost a month before the transmitter melted down. When I contacted them I received a chain email saying that I had to supply all of this specific information (which was included in the original email) to get an RMA. I had to provide copies of the sales receipt in order for it to be covered by warranty. Somehow I thought when I bought Oregon Scientific stuff it would actually work longer than 30 days so failed to save my receipt. Nope, it's back to my tube and float, $3.99 at Wal-Mart.
