The first one arrived defective and did not charge. The second one they sent as a replacement for the first stopped working in just under 1.5 years. I replaced it with a UPS of another brand (APC).

It is too early to give an opinion.... It is quiet, so far everything is good, it will show over time.

It broke down after almost 2 years of hardly any use. The battery does not charge in this machine and therefore it cannot do its job. While it was working, it was good.

For its category, the size is normal. It is quiet even when I have connected a computer with a 750-watt power supply in a gaming system. If the power goes out, you have enough time to shut down the machine smoothly.

I have it for a while and I can't judge yet. When the power goes out, its performance is 5 stars, I rate it for its build quality. It's quiet and reliable so far. In 2-3 power outages, it did the job, but because my work is delicate, as soon as the power goes out, I immediately shut down the PC to not lose progress. So, I hardly use it with the power cut, so I don't know how long it lasts, but I don't care. I just want to be able to shut down the PC in time. It is very good and reliable for now!
