Product review (4 stars): Quite accurate, but relatively short life
AcuRite has made this product for many years and it remains unmodified over that time. I purchased one from Lowe's 5 years ago. I found it to be quite accurate. However, like so many things these days, they're made in China and have the typical Chinese durability, and it comes with a modest 1-yr. warranty. Two weeks ago, it started reporting temps that were 5-6 degrees higher than what another wired station said, and eventually stopped changing the temp at all. Changing the batteries in both the sending and receiving units did not solve the problem, and the sending (outside) unit stopped blinking, meaning it was no longer sending updates to the receiver. So I just purchased another one, also from Lowe's, because the price was only $9.99, but not sure it should have been; the price tag on the bin was almost $16, but at checkout, I paid only $9.49 after my Lowe's credit card 5% discount. Either the bin price tag is wrong or the computer checkout price is wrong, or it's an unidentified sale item.

In any case, this product is quite accurate and works well. . . for about 5 years. Based on my experience, if it lasts beyond 5 years, it's on borrowed time.
