Extra Sensor for my C83349 Weather Station By LaCrosse

It's always nice to have an extra one on hand, especially if you live in a climate that is harsh at times. My last one lasted almost 3 years outside. It was under cover but still exposed to the atmosphere. Highly recommended!

Great Customer Service

Product was delivered on a very timely basis. It ended up being the wrong product for my needs and the company took it back with no problem. I spoke with a technician prior to returning it. He tried his best to help me to see if we could get the product to work to no avail. So I returned the item and the credit was issued as soon as they received it back. Very pleased with the transaction.
