I just went to their web site and ordered a New unit for the outside transmitter. They are having a 4th of July sale at reduced prices with an additional 17% off .. Instead of almost $90 it cost $65 They have parts to repair them yourself - Just did not know what to order as my unit started eating 4 batteries every two weeks and should last up to Two years -- I like having the Temp, Humidity, Barometer, Wind speed and direction, Rainfall , Heat index, Future forecast and record keeping data that can be linked to a smart Phone
