The product does what it's supposed to do, it measures the ambient temperature correctly. Unfortunately, the connection with the TP08 is not very good. The plug tends to pop out a couple of millimeters, leading in a false reading (>100 degrees to high), or the error message HHH, indicating too much heat. For now I have been able to use the product, using a rubber band to hold it in place. It works, but it's not ideal.
always good to have some spares
