The UPS 2000 Line-Interactive 2000VA 1200W with 2 Schuko Outlets by NG is a Tower UPS with 2 Schuko outlets. Its operation is (VI) Line-Interactive, which continuously adjusts the output voltage through an automatic voltage regulator, protecting against voltage fluctuations and power outages.

During the first 6-7 days, we had it on the balcony (with open windows) until the glue smell (or whatever plastic smell) stopped. Many devices smell when they operate for the first time, but this one exceeded to the point where you don't want to be in the same room. After the first week, we were finally able to bring it inside the room, although the problem disappeared completely slowly and gradually after about a month.
The device is bulky and somewhat ugly (although the latter is somewhat subjective). Anyway, it did its job when I needed it one day when the power company had continuous outages and brownouts. The UPS beeped to notify, but the computer didn't notice anything.
At this point, I want to emphasize that this specific UPS is not a pure sine wave, so it is connected to an older computer with correspondingly lower requirements (i.e., NOT active-PFC like newer power supplies, at least the good ones).
This means that it is NOT recommended for new computers with good power supplies with active-PFC as they can cause problems. Active-PFC power supplies require pure sine wave power, otherwise: a) they may shut down whenever the battery is used, b) even if they don't shut down, as long as the battery is operating, they will try to correct the waveform's half-cycle and struggle, resulting in reduced power supply life, extra noise, and possible overheating depending on various factors.
For a new computer, I got the Cyberpower 1500VA (CP1500EPFCLCD), pure sine wave and with a larger battery/capacity. Completely different category of UPS, but of course, triple the price. In any case, for a new computer (but also to be able to keep it in the future), I recommend a pure sine wave UPS.
They suggested it to me and I gave it a chance, very good in terms of price and performance, with no sudden voltage drops that would cause any device to turn off, and when the power went out, it lasted comfortably so I could shut down all my devices (PC, monitor, TV). I recommend it without fear
All good with this ups and very nice screen and good autonomy when there is no power BUT here, for the past 25 years that I have been using ups, it is the first time I see a ups that is considered "good" not having a communication port with the pc and it says it is optional - what is the point of having a ups with which your computer does not communicate, so you cannot configure it to shut down on its own for protection when there is no power. A well-known Athens chain of stores that sold it to me and deals mainly with computers and peripherals, when I asked them at least to sell me an extra optional USB port, they do not even answer if they have this optional port or not, probably because either there is no representation of this ups in Greece or if there is, it does not have this optional communication port with the pc.
