Great idea, Kent.
Think we all know what a clear plastin bad is!
Somebody advised me to switch to Lithium batteries, but just in the remote, two
AA batteries, outdoors (the sender).
Did that, indoor display showed the temp...for an hour and then got "--" again.
So since I had to buy a four-pack, tried to put the other two in the Receiver.
But the Receiver takes two
AAA 
---> la Crosse unit.
insulation must betoo thick for the radio signal to penetrate
Really? My (other) Bios weather station works great.
Never get the "--", and it receives through insulated house walls from over 100 feet away.
I think we've both just got crappy, cheap, made in who-knows-where units.
