as a consumer, I have got used only once to deduct 30% of the "manufacturer promise" and then decide whether to buy a product or not. The company TROTEC would thus fortunately do gross injustice! Before buying I sat down in detail with the manufacturer's instructions on the HP apart (and disputed), but can confirm that the device quite unspectacular does what is given. I waited with my review consciously 5 months, in order to confirm after this time that the unit is still working reliably, as the day: No increased fan noise, no vibration, etc. Originally purchased in order to get a "sunken" Kelle area dry again, the good news is in the meantime offset a used as an office storage room in continuous use for air conditioning. Adverse conditions: I am Strong pipe smoker ....
The only-not criticism, but if the manufacturer is reading suggestion: I'd an additional variant of the device want with integrated timer and a (functioning) display for the rel. Humidity (Surcharge 59,95 Euro). Why? When using I have described, the booth must be nich always corrected to 55% rh. Since in the absence may sometimes prevail 65% RH -The saves electricity! Thus, one could dry out 45% in timer mode to, for example, and then allowed to rise again to 60%, with no noise pollution during the use of the room humidity. Well, I've solved with an external timer and meter -geht also.
