Incredibly smelly. For about 2 months, the smell was in the whole apartment. And even now, if the windows are closed, then in the evening, when you come home, you can smell it. A huge minus is that Windows does not see it in any way. Only a third-party utility that still needs to be run at startup. Those. Windows UPS cannot be managed.
I decided to add some photos to help readers get a better sense of what I experienced.
