Does brilliantly what it's supposed to do. Seems pretty accurate, as the one that deviates most (± 1%), against my 3 calibrated hygrometers.
Works well. Maybe the fan could be a little quieter and the instructions clearer. But it does what it's supposed to.
Always good.
Very nice.
The parcel arrived well. The only flaw: there is only one plug for the 12V-connection on the device, not two - but it works perfectly.
