So far so good.
I’ll give the PT30 five stars because during the initial tests it has performed as advertised. During a 24 hour test it cooled quickly, got down to the set temps of 0 and 34 and held them, and was energy efficient. Current draw was 24w eco and 33w max. The compressor was on 50-60% of the time although there is some current draw all the time. I like the dual zone. Setting and reading the temps is simple with the controls, but using all the features is easiest with the app.
Construction of the PT30 seems sound. Time will tell. I believe the lid is hollow as it gets cool to the touch and is probably the weak point of insulation qualities. This is common in refrigerators and coolers. I may buy the insulated cover.
One other important thing…the unit is satisfyingly quiet, better than I expected.
