Query: Bad product, worse customer service

We've had this unit for less than a year and it has stopped working. We've replaced the batteries in both the main unit as well as the temp/humidity transmitter multiple times, but to no avail. We tried contacting the manufacturer (La Crosse Technology) but never received a response. We do NOT recommend this product and will not be purchasing any of La Crosse Technology's other products in the future.
