They stole the batteries for the Testo.
They opened my case added some stupid adaptor for a plugin. Then opened my bag with good batteries and left the bag in the case. Dont buy from these guys its a trash scam. Only reason why i order it was because of the delivery date was different from all the others. I needed it sooner than later.

Sub cooling and superheat readings
Many more refrigerants can be checked than with a gauge manifold.
