Before this unit, I had almost equivalent Supra brand: DU200, which announced 20l / day. I thought, "Who can do more, can do more" and I bought this when my Trotec Supra decided to go to heaven dehumidifiers (via the box recycling course). 5 years of loyal service were right to health. I hope the TTK100E will live as long but I doubt ... Indeed, I have not had the "Deutsche Qualitat" feel lets hope the manufacturer. Let's break the myth right away: made in China for this more modern equipment than my old camera yet at least as loud, if not more. While these devices make noise, but what is not normal, or at least what is not acceptable is that this noise is partly caused by vibrations from the chassis. I think we wanted to build cheaper, so there are no elements to wedge the outer casing on the compressor where vibration, hence noise. Level efficiency, it is not better than my Supra is sometimes significantly worse, evidence is residual moisture of towels, which was not the case "before" (the unit is in a bathroom). The positive anyway: very simple to use, accurate hygrometer and programming function of convenient operating time. I have realized that for the camera (too late) that the opaque tray is not progress. You do not see the water level rise, which allow to anticipate emptying. Too bad for me, I just had to be alert to this detail. So I note quite severely the machine. This does not mean that the camera does not work well but reflects disappointment with the expectations for a purchase in this price range. Thank you for having me read.
