Mine took 13 months. If it worked, it did a good job. I wish there were a few more icons on the small display to make the menu system more intuitive, but I think it's what you'd expect from a cheap one. BUT once the temperature dropped by 15 degrees. It may not seem like much, but in my case everything is frozen. I found that the problem was with the thermistor at the end of the probe. I bought another one, but this time a model with an interchangeable probe. In my application it doesn't matter if it fails. But I certainly wouldn't count on him to keep my grandmother alive. It's weird to give this device a bad review and buy another one. I think I've decided to treat it as a one-off product, but the rating in the review reflects the fact that it's not advertised that way. Therefore, the rating has been updated to 3 stars.
