I'm on my third one, first was the engel white one, cable hung inside cabinet with dual readout on the unit,,cable broke on many ocasions,
Second was the engel two part unit, red one, not worth it, could not get a reading from the fridge while it was in the back of the ute,.
Third one is the everkool branded unit, perfect,only short cable to hang inside the cabinet, good range from transmiter to reciever and very clear readout,,
