The machine is surprisingly loud for the size. We can not use it in the bedroom at night for that reason. It therefore disturbs while watching TV, listening to music, etc.
But this is the MAJOR problem, so Mentioned in other reviews: The Automatic mode is flawed. First of all, acording to the users manual, the TTK 70S is not designed to keep "very low humidity levels", by deed meaning under 55-60%. This is a problem: because of a series reasons:
1. This level might not be low enough for some people. In our case we quietly get moldy walls at 60%.
2. The Amazon product description (before you buy it) does not warn you about that! It only says it works from 49%. This is misleading advertising !!!
3. The internal hygrometer Seems to not to work properly anyway, so the machine stops dehumidifying Often at 63-64% humidity.
To add to the misery, When the "low level" of humidity is reached the maching stops dehumidifying But The fan stays on, wasting precious energy and Maintaining the annoying loud high levels.
On the brightside, When You put it on manual mode ("continuous") it does dehumidify quite well! And it does go down to 49% if you want. I gave the two stars for that. But you must always keep an eye on it to switch on and off, and to change the water tank, Because The continuous mode is designed for use with a trouser connected to the sink, so beware, it will not stop working When the tank is full!
I'm personally returning the machine.
Hope this helps;)
