- I bought 3 years ago 4 pieces for a private house. First of all, I liked the price, because at this price there are no analogues. With almost round-the-clock work, out of 4, the control board of one burned out, which is why I bought it as a replacement entirely. Over the past 3 years, the price has almost doubled :-(
- Noisy. Moreover, it is the noise of the air flow that is especially annoying when switching in complete silence - sleeping with it is not an option.
