I'm sure this sensor works very well. The problem is that I was looking for a replacement sensor for my Acurite base model 00611A3. On the Acurite website, the replacement sensor is listed as 00609A1TX. Enter this number on Revain's website and you will receive the transducer that was sent to me. Acurite 06002M or otherwise listed as 00592TX which will NOT work with my 00611A3 base. I assumed (stupidly) that the reference was to the correct sensor. If I had read some reviews I would have seen a link to 00592TX and suspected something was wrong. In any case, Revain processed the refund straight away and I received a credit to my account (which is a big part of working with Revain's fantastic support team). I ended up buying a brand new monitor and a 00611A3 sensor as my other base works with the sensor too. Now my wife can see the temperature in her office instead of yelling at me to read the temperature on the kitchen monitor. :-)
