"I purchased an AcuRite 609A1 weather station from Lowe's on 10/6/12. In early July 2013, the display began showing 1% humidity whenever the temp got above 90 degrees. I called their CS to see about a replacement sensor under warranty. I'm pleased to say the rep was very courteous. She asked me to e-mail a copy of the receipt (KEEP YOUR RECEIPT!!), which I received a new sensor in about 5 days. Great service/no need to return the malfunctioning sensor.

This raises questions about the durability of the product, but I won't know if that's a serious issue until I've had the new sensor for a while.

One frustration: They do not offer any stations with multiple displays running from one sensor, a major shortcoming in their product line."
